To update a drive, complete the following fields and then click Finish, or click Cancel to end this task.
Enter the Fibre Channel world wide name of the drive if the drive is going to be accessed by a data mover for outboard copy operations. If the drive contains the world wide name, this should only be specified if the drive became defective and was replaced with another drive. The Fibre Channel world wide name can be updated to preserve the drive and associated path definitions.
Enter the serial number of the drive being updated. The possible values are:
serial number | Specify the serial number for the drive. |
Autodetect | Specify that the serial number will be automatically detected if a path has already been defined to this drive |
If a path to this drive has already been defined, and you enter a serial number, then the number you enter will be compared to the number detected by Tivoli Storage Manager. If the numbers do not match, then this command will fail.
Enter the element address of the drive being updated. This field is valid only for drives in SCSI libraries when the operation is performed from a server that is a library manager. The possible values are:
address | Specify the element address for the drive. |
Autodetect | Specify that the element address will be automatically detected if a path has already been defined to this drive. |
If a path to this drive has already been defined, and you enter an element number, then the number you enter will be compared to the number detected by Tivoli Storage Manager. If the numbers do not match, then this command will fail.
If the library in which the drive is located does not support the Read Element Status SCSI command and ELEMENT=AUTODETECT, then the command will fail with a Tivoli Storage Manager error message.
The server needs the element address to connect the physical location of the drive to the drive's SCSI address. To find the element address for your library configuration, consult the device manufacturer's information.
Select the value of the drive's online state. This parameter is optional.
Do not specify other optional parameters along with ONLINE=YES or ONLINE=NO, because the drive will not be updated and the command will fail when the drive is in use.
Available options are the following:
Yes | Specifies that the drive is to be available for use. |
No | Specifies that the drive will not be online. |
This command can be issued when the drive is involved in an active process or session, but it is not recommended. This command allows drives to be taken offline and used for another activity, such as maintenance.
If you make the drive offline while it is in use, the drive will be marked offline. However, the mounted volume will complete its current process. If this volume was part of a series of volumes for a given transaction, the drive will no longer be available to complete mounting the series. If no other drives are available, the active process may fail.
The updated state will be retained even when the server is halted and brought up again. If a drive is marked offline when the server is brought up, a warning is issued noting that the drive must be manually brought online. If all the drives in a library are updated to be offline, processes that need a library mount point will fail, rather than queue up for one.
Enter the value for the cleaning frequency you would like to establish for the selected drive. This parameter is not valid for externally managed libraries, for example, 3494 libraries or STK libraries managed under ACSLS.
The following are possible values:
None | Specifies that the server does not track the need for device cleaning. Some libraries have their own automatic cleaning. |
Asneeded | Specifies that the server loads the drive with a checked-in cleaner cartridge only when a drive reports to the device driver that it needs cleaning. |
Gigabytes | Specifies a value in gigabytes, from 1 to 9999. This indicates how much data processing will occur before the server loads the drive with a cleaner cartridge. Drive cleaning will still take place when a drive indicates that cleaning is required. |
