You can delete only the
last logical drive that was configured. This is because of how the
SCSI device files are associated with logical drives, and because
logical drives are always sequentially numbered beginning with 0.
Here is an example to illustrate this:
You have logical drives 0, 1, and 2 configured, with file
systems mounted to each of the logical drives, as follows:
File system /raid/disk0, /dev/dsk/c0t0d0 → logical drive 0
File system /raid/disk1, /dev/dsk/c0t1d0 → logical drive 1
File system /raid/disk2, /dev/dsk/c0t2d0 → logical drive 2
If you were able to delete logical drive 1 (which is not the last logical drive that was
configured), then logical drive 2 would be renumbered to logical
drive 1. This would give you the following:
File system /raid/disk0, /dev/dsk/c0t0d0 → logical drive 0
File system /raid/disk1, /dev/dsk/c0t1d0 → was logical drive 2
File system /raid/disk2, /dev/dsk/c0t2d0 → no logical drive
This would result in the /raid/disk1 file system reading from and writing to the data
that was previously in the /raid/disk2 file system, which would not be correct.
The steps to delete a logical drive are described below. Note that these steps assume you have started
IRM and (if applicable) selected the HP RAID 4Si controller the
logical drive is configured on.
Menu path: "Management
Menu" → Configure → Delete Last Logical Drive
A warning dialog box displays, and you are asked if you want
to proceed to delete the logical drive.
If you do not want
to delete the logical drive, highlight NO and press the Enter key. You are placed back in the "Configure" menu;
go to step 2.
If you want to delete the logical drive, highlight YES and press the Enter key. The last logical drive that was configured is deleted
from the controller's configuration. After the drive has
been deleted, a confirmation message displays. Press any key to
continue. You are placed back in the "Configure" menu;
go to step 2.
Press Esc; you are placed back in the "Management Menu."
Press Esc; an exit confirmation dialog box displays.
Highlight YES and press Enter; IRM ends.
