1. As root, find the scsi disks.

	lscfg | grep hdisk
Example:
root@celtics>> lscfg | grep hdisk
+ hdisk0           U7311.D20.101730B-P1-C08-T2-L8-L0                            16 Bit LVD SCSI Disk Drive (73400 MB)
+ hdisk1           U7311.D20.101730B-P1-C08-T2-L9-L0                            16 Bit LVD SCSI Disk Drive (73400 MB)
* hdisk2           U7879.001.DQDHYVM-P1-C1-T1-W50060168302001F5-L0              EMC CLARiiON FCP RAID 1/0 Disk
* hdisk3           U7879.001.DQDHYVM-P1-C1-T1-W50060168302001F5-L1000000000000  EMC CLARiiON FCP RAID 1/0 Disk
* hdisk4           U7879.001.DQDHYVM-P1-C1-T1-W50060168302001F5-L2000000000000  EMC CLARiiON FCP RAID 1/0 Disk
* hdisk5           U7879.001.DQDHYVM-P1-C1-T1-W50060161302001F5-L0              EMC CLARiiON FCP RAID 1/0 Disk
* hdisk6           U7879.001.DQDHYVM-P1-C1-T1-W50060161302001F5-L1000000000000  EMC CLARiiON FCP RAID 1/0 Disk
* hdisk7           U7879.001.DQDHYVM-P1-C1-T1-W50060161302001F5-L2000000000000  EMC CLARiiON FCP RAID 1/0 Disk

2. One at a time, set the disk to flashing.

	diag

3. Once inside the diag utility, hit <ENTER> to get
past the "DIAGNOSTIC OPERATING INSTRUCTIONS" screen.

4. In the "FUNCTION SELECTION" menu, choose:

	Task Selection (Diagnostics, Advanced Diagnostics, Service Aids, etc.)

5. In the "TASKS SELECTION LIST" menu, choose:

	Identify and Attention Indicators

6. In the "IDENTIFY AND ATTENTION INDICATORS" menu, select the
identifier associated with one of your scsi hdisks by going to a
specific hdisk, hiting <ENTER>, and, then, hitting <F7>.

For example, from above, hdisk0's identifier is:

	U7311.D20.101730B-P1-C08-T2-L8-L0

The disk's indicator light will now be flashing.
By setting it to flashing, an "I" will be in the left-hand column beside
the name.

Example:

I U7311.D20.101730B-P1-C08-T2-L8-L0

7. To unselect the disk, use the same method as you 
did to select it in step 6.
