SSA RSM - Event Data Table Contents
Service Request Numbers (SRNs)


Dynamic SRNs

Note: An X represents a digit 0 through F.
e.g. 1XXXX would be any SRN with its most significant bit equal to 1.
This SRN should only be acted upon if no exact SRN exists.

Note: SRNs containing the three least significant bits equal to PAA correspond to the Port and Address of the device, where Port maps to the table below, and Address is the device number on the loop starting at device 0.
e.g. 20PAA, 20303 would correspond to the fourth device on the loop from port B2.

Action: Install the correct adapter microcode for this cache card.

42524 Fast-Write Cache Option Card (100%) Description: A fast-write disk drive (or drives) that does not contain synchronized data has been detected. The Fast-Write Option Card, however, cannot be detected. The disk drive (or drives) is offline.

Action: Go to the SRN table in the user or maintenance information for the SSA device and follow the instructions for this SRN.

42525 Fast-Write Cache Option Card (100%) Description: A fast-write logical disk contains unsynchronized data, but the Fast-Write Option Card does not contain that data. One of the following conditions occurred:
  1. The data was not synchronized on the old adapter before the disk drive was moved to this adapter.
  2. The wrong Fast-Write Option Card was installed onto this adapter.
  3. The Fast-Write Option Card lost data because the battery failed, or the data in the cache was deleted.

Action: The failing disk drive is offline.

  • If the disk drive has just been moved from another adapter, do either of the following actions :
    • Return the disk drive to its original adapter.
    • Move the original Fast-Write Cache Option Card to this adapter so that the data can be synchronized.
  • If the wrong Fast-Write Cache Option Card has been installed (for example, if the adapter has been exchanged, but the original Fast-Write Cache Option Card is still on the old adapter card), install the original Fast-Write Cache Option Card onto this adapter.
  • If the adapter card has been switched off for more than seven days, the battery is discharged and data has been lost. If the adapter card has been switched off for fewer than seven days, exchange the cache card for a new one, then do the following :
    1. Ask the customer to disable the Fast-Write option for :
      • Each device for which the Fast-Write option is offline.
      • All other devices that are connected to the failing adapter have the Fast-Write option enabled.
      For instructions on how to disable the Fast-Write option, see "Dealing with Fast-Write Problems" in your Maintenance Guide.
    2. If the Fast-Write option has been disabled for a RAID-5 array, the system disk for that array can no longer be configured. Delete the RAID-5 array, then recreate it. For instructions on how to delete the array, see "Dealing with Fast-Write Problems" in your Maintenance Guide.
    3. Ask the customer to re-enable the Fast-Write option for the devices that are attached to the Fast-Write Cache Option Card.
42527 None Description: A dormant fast-write cache entry exists.

Action: The fast-write cache contains unsynchronized data for a disk drive that is no longer available. If possible, reconnect the disk drive to the adapter to enable the data to be synchronized. If you cannot reconnect the disk drive (for example, because the disk drive has failed), the user should delete the dormant fast-write entry. Go to the SRN table in the user or maintenance information for the SSA device and follow the instructions for this SRN.

42528 None Description: A fast-write disk drive has been detected that was previously unsynchronized, but has since been configured on a different adapter.

Action: If the disk drive contains data that should be kept, return the disk drive to the adapter that it was previously connected to.

If the disk does not contain data that should be kept:

  1. Ask the user to delete all offline items. Go to the SRN table in the user or maintenance information for the SSA device and follow the instructions for this SRN.
  2. Change the use of the disk drive as appropriate. Go to the SRN table in the user or maintenance information for the SSA device and follow the instructions for this SRN.
42529 Fast-Write Cache Option Card (100%) Description: Cache Inactive - Battery Charging.

Action: The battery is in fast-charge. The battery will be in fast-charge for up to 60 minutes after the adapter has been powered on. During this time the cache will remain inactive. (Inactive, means that fast-write disks can still be accessed but they will not be utilising the fast write function).
If this condition persists for more than 60 minutes after the adapter has been powered on, replace the cache card.

4252A Fast-Write Cache Option Card (90%)

  • Run diagnostics on the partner system and fix problems before re-testing this system.
43PAA Disk drive (90%)
SSA attachment (10%)
Description: An SSA device on the loop is preventing the completion of the loop configuration.

Action: Use RSM to determine which device is preventing configuration (see the user or maintenance information for your SSA device). The device that is preventing configuration is the device that is beyond the last-configured device on an open SSA loop.

44PAA Disk drive (100%) Description: A Disk drive has a "Failed" status.

Action: Use RSM to find the failing Disk drive (see the user or maintenance information for your SSA device). If no device is listed with a status of "Failed", use the PAA part of the SRN to determine which device is failing. Before you exchange the failing device, run concurrent diagnostics to that device to determine the cause of the problem.

45PAA Disk drive (40%)
SSA attachment (40%)
External SSA cables, Fibre-Optic Extenders, or fibre optic cables (18%)
Frame assembly (2%)
Description: The SSA attachment has detected an open SSA loop.

Action: Use RSM to determine which part of the SSA loop is failing. (see the user or maintenance information for your SSA device).

46000 None Description: A RAID array is in the Offline state because not enough disk drives are present in the array to miantain data availability. For RAID-0, at least one member disk drive of the array is missing. For RAID-5, at least two component disk drives are missing.

Action: Go to the SRN table in the user or maintenance information for the SSA device and follow the instructions for this SRN.

46500 None Description: A member disk drive is missing from an array, or the remote NVRAM is not available.

Action: The array is in the Offline state. Find the missing member disk drive or the other adapter card. If these cannot be found, delete the array, then recreate it.

47000 None Description: An attempt has been made to store in the SSA attachment the details of more than 32 RAID arrays.

Action: Go to the SRN table in the user or maintenance information for the SSA device and follow the instructions for this SRN.

47500 None Description: Part of the array data might have been lost.

Action: Go to the SRN table in the user or maintenance information for the SSA device and follow the instructions for this SRN.

Action: Go to the SRN table in the user or maintenance information for the SSA device and follow the instructions for this SRN.

48500 None Description: The array filter has detected a link configuration that is not valid.

Action: Go to the SRN table in the user or maintenance information for the SSA device and follow the instructions for this SRN.

48600 None Description: One member disk drive of an array is not on the SSA loop that contains the other member disk drives of the array. The array is in the Exposed state.

Action: All the member disk drives of an array must be on the same SSA loop. Find all the members of the array. Go to the SRN table in the user or maintenance information for the SSA device and follow the instructions for this SRN.

48700 None Description: Multiple member disk drives of an array are not on the SSA loop that contains the other member disk drives of the array. The array is in the Offline state.

Action: All the member disk drives of an array must be on the same SSA loop. Find all the members of the array. Go to the SRN table in the user or maintenance information for the SSA device and follow the instructions for this SRN.

48750 The adapter cannot access the other adapter in the loop and either:
the secondary half of the array can be seen by the adapter and Split Array Resolution is set to Primary or the Primary half of the array can be seen by the adapter and Split Array Resolution is set to Secondary.

This can be caused by a power failure on one half of the array or a break in the SSA loop betwwn the two domains of the array.

Description: The array is offline because the primary/secondary domain of the array is not present.

Action: This can be fixed by restoring power to the missing domain of the array or repairing the broken loop that is preventing access to the other disk drives.

If the other domain of the array has become permanently unavailable as a result of a disaster, access to the remaining domain of the array can be forced by changing the Split Array Resolution attribute however, this should only be performed by the user if he can guarantee that updates to the other domain of the array will not be performed. See the Split Array Resolution section in your adapter User Guide and Maintenance Information Manual before performing this operation.

  1. Select the array from the Logical View
  2. Select the Modify Attributes action and change the state of the Split Resoultion attribute.
48755 This may have been caused by :
  • Failure of an adapter AND a logical disk.
  • A RAID member being connected to another SSA adapter(s)
  • Split domain configuration where only one adapter is configured and the adapter fails along with all the Primary or Secondary disks.
Description: One member of a RAID 1 array has been detected but the adapter is unknown to the array member, or all the Primary or all the Secondary disks of a RAID 10 array are present but the adapter is unknown to the array.

Action: If this problem has resulted from an unintentional change to the system configuration, restore the system to its original configuration. If the problem has resulted from an adapter failure AND the failure of the members of one domain of an array then perform the following actions to attach the array to the adapter.

  1. Select the array from the Logical View
  2. Select the Modify Attributes action and change the state of the Split Resoultion attribute.
  3. The array will now become available but will remain in the exposed or degraded state until the missing array members have been added.
48760 This can be caused if a RAID 1 or a RAID 10 array has been split exactly in half (by domain) and a write operation has been performed independantly to both domains of the array. Description: The array is offline because the split/join procedure was not performed correctly.

Action: The data on the array is inconsistent. See the Split Array Resolution section in your adapter User Guide and Maintenance Information Manual before attempting to recover the array.

48800 None Description: The Invalid-strip-table is full. Because of failures on multiple member disk drives of an array, no access to the data on the array is possible. The failed array is in the Offline state.

Action: Go to the SRN table in the user or maintenance information for the SSA device and follow the instructions for this SRN.

48900 None Description: An array is not available; multiple devices have failed. Multiple disk drives failed during an array building operation.

Action: Run diagnostics and the Certify service aid to all the disk drives that were used to create the array. If problems occur, correct these problems before you attempt to recreate the array.

48950 Disk drive (100%) Description: A disk drive has caused an array building operation to fail.

Action: Go to the SRN table in the user or maintenance information for the SSA device and follow the instructions for this SRN.

49000 None Description: An array is in the Degraded state because a disk drive is not available to the array, and a write command has been sent to that array.

Action: A disk drive might not be available for one of the following reasons:

  • The disk drive has failed.
  • The disk drive has been removed from the subsystem.
  • An SSA link has failed.
  • A power failure has occurred.
Use RSM to find any failed disk drives, failed SSA links, or power failures that may have caused the problem. Go to the SRN table in the user or maintenance information for the SSA device and follow the instructions for this SRN.
49100 None Description: An array is in the Exposed state because a disk drive is not available to the array.

Action: A disk drive can become not available for several reasons:

  • The disk drive has failed.
  • The disk drive has been removed from the subsystem.
  • An SSA link has failed.
  • A power failure has occurred.
Use RSM to find any failed disk drives, failed SSA links, or power failures that may have caused the problem. Go to the SRN table in the user or maintenance information for the SSA device and follow the instructions for this SRN.
49500 None Description: No hot spare disk drives are available for a RAID array that is configured for hot spare disk drives.

Action: Use RSM to find any failed disk drives, failed SSA links, or power failures that may have caused the problem. Analyse the Event Log for any SSA devices which have failed and follow the instructions if an SRN is provided.

49510 SSA loop configuration problem. Description: Hot-spare configuration is not synchronized.

Action:

  • This problem has occurred because the cabling has changed or because new hot-psare disks have been added to the loop.
  • If the changes were not intentional restore the system to its original configuration.
  • If the changes were intentionl select the Hot-spare Pool List via the adapter which raised the SRN.
    Select each unsynchronized pool, and either Add more hot-spare disks or modify the attributes to reduce the Minimum hot-spares value.
49520 An array member has used a hot-spare from a pool other than its specified pool. If the hot-spare pools have been correctly configured this indicates that more than one disk drive may have failed.
Disk drive module 100%
Description: Hot-spare optimization has been lost.

Action:

  1. Select the Hot-spare Pool List via the adapter which raised the SRN.
  2. Select the pool with a status of Mixed.
  3. Note the array name and disk serial number that are listed as being in the Wrong Pool. (This array component will be exchanged later in the procedure after all rejected disk drives have been replaced.)
  4. Goto RSM and "delete" any rejected resources, and note their disk serial number. If the disk is not rejected it may have failed. Replace the FRU and proceed to step 5.
  5. The disk with the serial number noted in step 3 should be exchanged for the disk with the serial number noted in step 4. (or the new disk if the disk was replaced). To do this, from the Logical View select the array noted in step 3. Select the component disk as noted in step 3. On the disk view, select Exchange Component. When presented with the candidate list, select the disk with the serial number noted in step 4. (or the new disk if the disk was replaced).
49530 The minimum number of hot-spares in the assigned pool is greater than the number of hot-spares currently in the pool. Disk drive module 100% Description: Less than the specified number of disks remain in a hot-spare pool.

Action:

  1. Goto RSM and "delete" any rejected resources. Note their disk serial number. If there are no rejected disks, a drive may have failed. Replace the FRU and proceed to step 2.
  2. Select the Hot-spare Pool List via the adapter which raised the SRN.
  3. Select the pool with a status of Empty, Reduced or Critical.
  4. Add hot-spare resources to the pool. Either the disk(s) noted in step 1, or any new disks have replaced failed resources.
49540 Hot-spares have been assigned to pools other than pool zero but other adapters on the SSA loop are using versions of microcode that do not support hot-spare pools. Description: Adapters detected that do not support hot-spare-pools.

Action:

  • This problem has occurred because the cabling has changed or because an SSA adapter that does not support hot-spare pools has been added to the SSA loop.
  • If the changes were not intentional restore the system to its original configuration.
  • If the changes were intentional either:
    • If the new SSA adapter is type LL05, upgrade to the latest version of microcode. (Use the CheckLevel function)
    • For all hot-spare pools connected to this adapter, select the Hot-spare Pool View and removed all components from the pool.
49700 None Description: The parity for the array is not complete.

Action: Go to the SRN table in the user or maintenance information for the SSA device and follow the instructions for this SRN.

Action: (IBM SSA RAID Cluster Adapter Only) Use RSM to check the SSA loops for invalid connections and run adapter diagnostics.

4C800 None Description: Only one member of a RAID 1 array is present, and its owning adapter serial number does not match that of this adapter.

Action: (IBM SSA RAID Cluster Adapter Only) Do one of the following actions:

  • Install the other member of the array onto this SSA adapter.
  • Remove the array member from this SSA adapter.
  • If you want to continue to use the one member on this SSA loop, go to, and set the Split Resolution field to the member number of the array member that you want to use.
4E000 Disk drive (100%) Description: Data scrubbing has reconstructed a data block and reassigned the affected blocks.

Action: If this SRN occurs three times in 24 hours, exchange the FRU for a new FRU.

4F000 None Description: The SSA adapter has detected duplicate resource numbers.

Action: The disk drive that has the duplicate resource number has been designated as a "new" resource. Use RSM to reattach the disk drive in the required position.
Note: In RSM, the resource can be found in the System (AIX) list, which corresponds to the usage of "new".

4F101 None Description: Both members of a RAID 1 array are indicating that they have been updated while the other member was not available. The UID/array name of the member that was not available is reported. (A corresponding SRN 4F100 is also logged.)
