30 Using the CLI
Deleting spares
Basic command
delete spare unit <#> <diskrange>
Command options
unit #—the unit that will no longer have access to the spare. This is the same number that was given
to the unit when it was created with the add unit command.
diskrange—the spare drive or range of spares to remove from use. Disks are identified by box
number and bay number.
Example command
CLI> delete spare unit=2 disk109
Recognizing a failed unit
If all drives of a previously failed unit are in working order, use this command to change the state of the
unit back to VOLUME_OK.
To accept media exchange on a unit marked as failed:
Basic command
accept unit <#>
Command options
#—the unit that you want to activate, where # represents the unit number.
Expanding an array
CAUTION: In an HP-UX environment, expanding a LUN, as described in this section, is not supported.
See the HP-UX documentation for instructions on expanding LUNs on an HP-UX system.
To add additional physical drives to an array:
NOTE: Because this command affects the entire array, all LUNs made from the array are also affected.
Basic command
expand unit <#> <diskrange>
Command options
#—one of the LUN within the target array.
NOTE: Any LUN in the array can be entered to identify the array; the space is added to the array and not
the LUN.
diskrange—the physical disks to add to the array. Disks are identified by box number and bay
number.
Example command and response
CLI> expand unit 4 disk204-disk207
The actual new array capacity will be 3000MB.
The array with Unit 4 is being expanded.
Use “show unit 4” to monitor progress.
