ServeRAID controller messages

This section lists the ServeRAID messages that might appear during system startup. The ServeRAID controllers provide a Device Event Log that collects statistics on the number and types of events that occur on a selected physical drive. After correcting a problem with the disk array, clear the log so that you can identify any subsequent errors quickly.

All physical drives contain unique identifiers, such as the drive serial number and manufacturer. During configuration, the ServeRAID controller stores this information.

Following are messages associated with the ServeRAID subsystem in alphabetical order.

Table 4. ServeRAID controller messages

Message	Explanation	Action
A new drive was installed.	When the ServeRAID controller detects a new drive that is not part of the current configuration, the following message appears:x new Ready drives found where x is the number of Ready drives found.	This is an information message. No action is required.
Auto rearrange.	Auto rearrange is enabled or disabled.	This is an information message. No action is required.
Battery-backup cache not responding.	BIOS code detected a bad or failed battery-backup cache.	Press F9 to remove the battery-backup cache from the configuration, or press F10 to exit without change.
Battery-backup cache replacement.	The ServeRAID controller detects that the battery-backup cache is defective.	Press F8 if you replaced the battery-backup cache, or press F10 if you have not replaced the battery-backup cache.
Configured drives are missing.	When the ServeRAID controller detects that a previously configured drive is missing, the following message appears: x Online drives not responding where x is the number of drives not responding. Example of a possible message: Online Drive on Channel 3 SCSI ID 3 is not responding.	Press one of the following keys: F2 Detailed description. Press this key for a detailed description of the problem. F4 Retry. Press this key after correcting a problem. For example, press F4 after you switch on the external storage enclosure that contains the physical drive. F5 Change the configuration and set the drives to defunct. Press this key to accept the new state that the ServeRAID controller will assign to the drive. For example, the ServeRAID controller will assign the drive a state of defunct or empty. You can also press F5 when you must remove a drive. RAID level-1 and RAID level-5 logical drives are present, and performance in a degraded mode is acceptable. The ServeRAID controller will assign the drive a state of defunct, but the server can complete startup. However, the array will remain in Critical mode and the potential for data loss will exist until you replace and rebuild the defunct drive. To prevent the loss of data, replace and rebuild the defunct drive in a timely manner. Note: A physical drive in the defunct state does not necessarily mean that you need to replace the drive. Before you replace the drive, ensure that: All cables are connected properly to the backplane and to the physical drive. Also, ensure that all cables inside the server are connected properly. The hot-swap drive trays are seated properly in the drive bay. If multiple drives fail in separate arrays (one physical drive per array), then replace each of the defunct physical drives. After you perform these steps, if the physical drive does not function properly, replace the drive. F10 Continue starting without changing the configuration. Press this key to continue without change to the configuration.
Configured drives are not in the configured location.	When the ServeRAID controller detects that a previously configured drive is present, but the drive is in a new location, the following message appears: x Online drive has been rearranged where x is the number of drives that have been rearranged. For example: Online Drive on Channel 3 SCSI ID 4 moved to Channel 3 SCSI ID 3.	Press one of the following keys: F2 Detailed description. Press this key for a detailed description of the problem. F4 Retry. Press this key after correcting a problem. For example, press F4 after you move the physical drive to its previously assigned location. F5 Change the configuration and set the drive to defunct. Press this key to accept the new state that the ServeRAID controller assigns to the drive. For example, the ServeRAID controller will assign the drive a state of defunct or empty. Note: A physical drive in the defunct state does not necessarily mean that you need to replace the drive. Before you replace the drive, ensure that: All cables are connected properly to the backplane and to the physical drive. Also, ensure that all cables inside the server are connected properly. The hot-swap drive trays are seated properly in the drive bay. If multiple drives fail in separate arrays (one physical drive per array), then replace each of the defunct physical drives. After you perform these steps, if the physical drive does not function properly, replace the drive. F5 Change the configuration and accept the rearrangement. Press this key to change the configuration to match the current drive location. You might remove the hot-swap drives from the server for security or maintenance reasons. If you replace the drives but install them in different drive bays, you can press F6 to accept the new locations, and the ServeRAID controller will update the configuration. F10 Continue startup without changing the configuration. Press this key to continue without change to the configuration.
Controller is not responding to commands. No logical drives are installed.	The ServeRAID controller is not operational.	Service the appliance.
New controller installed in a configured server or drives are imported.	When the ServeRAID controller detects that the identifiers of the drives do not match the controller configuration information, the following message appears: x Online drive(s) found with mismatch configuration	Press one of the following keys: F2 Detailed description. Press this key for a detailed description of the problem, such as the example messages above. F4 Retry. Press this key after correcting the problem. For example, press F4 after you move the physical drive to its previously assigned location, or after you install the original physical drives back in the server. F5 Change the configuration and set the drive to defunct. Press this key to accept the new state that the ServeRAID controller will assign to the drive. For example, the ServeRAID controller will assign the drive a state of defunct or empty. Note: A physical drive in the defunct state does not necessarily mean that you need to replace the drive. Before you replace the drive, ensure that: All cables are connected properly to the backplane or system board, and to the physical drive. Also, ensure that all cables inside the server are connected properly. The hot-swap drive trays are seated properly in the drive bay. If multiple drives fail in separate arrays (one physical drive per array), then replace each of the defunct physical drives. After you perform these steps, if the physical drive does not function properly, replace the drive. F7 Import configuration information from drive. Press this key to restart the server. Press this key to import the configuration information from the drive and to update the configuration information for the ServeRAID controller. This choice is useful when you replace the ServeRAID controller in an existing ServeRAID subsystem. You also might press F7 if you replace a whole set of drives with drives that were configured in another server with a ServeRAID controller. Note: When you install drives in a server that has no logical drives defined, the F7 choice will not appear. The ServeRAID controller does not contain any logical drives in its factory configuration. Therefore, F7 will not appear. In this case, do the following: Restart the server and press Ctrl+I to enter the Mini-Configuration program. Follow the onscreen prompts. Select Advanced Functions. Select Copy the Configuration from Drives to the Controller and follow the instructions on the screen.
Recoverable configuration error.	The configuration data stored in NVRAM does not match the configuration data stored in the EEPROM.	Press Ctrl+I to access the ServeRAID Mini-Configuration menu. Follow the onscreen prompts. Select Advanced Functions from the Main Menu. Then, select Copy the Configuration from Drives to the Controller. Follow the onscreen prompts.
Unrecoverable configuration error.	The configuration data stored in NVRAM does not match the configuration data stored in the EEPROM.	Press Ctrl+I to access the ServeRAID Mini-Configuration menu. Follow the onscreen prompts. Select Advanced Functions from the Main Menu. Then, select Restore to the Factory Default Settings. Follow the onscreen prompts. Note: Restoring to factory default settings sets all online drives in array to ready. You must import the configuration from the drives or diskette. Otherwise, you must create a new array, install the operating system, and restore data from backup.
WARNING: n logical drives are critical; n logical drives are offline.	One or more physical drives have failed.	Replace the defunct drives as soon as possible to prevent data loss.
Your server has an error due to a Blocked Logical Drive.	One or more logical drives are blocked. A blocked logical drive cannot be accessed.	Press F4 to unblock the logical drive, or press F5 to continue without unblocking.

ServeRAID ISPR, BCS, and ECS POST error codes

This section describes the ISPR, BCS, and ECS POST error codes. See Table 5 for ISPR codes and Table 6 for BCS and ECS codes.

Note:

When the ServeRAID controller requires your input, a list of function keys will appear below the message. Where sidor ch appears in these messages, sid is the SCSI ID for the device, and ch is the channel to which the device is attached. Where m or n appears in these messages, a number will appear in the actual message.

Table 5 contains information on ISPR codes.
