Find the entry in the log for the drive you want to replace.
6.
Record the location information for the drive.
Note:
The location information is in either of these forms:
0:0:5:0
In this example, 0 is the SCSI host number, 0 is the SCSI bus, 5 is the SCSI target ID, and 0 is
the logical unit number (LUN).
0/00-0E-02
In this example, 0 is the SCSI host number, 00 is the I/O adapter (IOA) SAS port, 0E is the
expander port, and 02 is the device port.
7.
If the drive you want to replace is unprotected or in use, move the data from the drive before
continuing with this procedure. If the drive is in a RAID 0 (non-redundant RAID array), after you
have moved the data, delete the RAID 0 before proceeding.
