Pausing Host Adapter Activity When Replacing Disks

Some drive enclosures allow you to remove and replace drives
while SCSI bus activity continues; others do not. If your drive enclo-
sure does not (check the documentation for the enclosure), use the
Hot Swap Pause option before you remove or replace any drives in
an array. Hot Swap Pause suspends activity on all SCSI buses (host
adapter channels) used in the array, thereby assuring data integrity
on the connected drives and arrays.
To use Hot Swap Pause, follow these steps:
1
If the system has only one array, skip to step 2. Otherwise,
from the System Menu select the array containing the disk you
are removing. The Main Menu for that array appears.
2
From the Main Menu, select Hot Swap Pause. A prompt
appears, asking you to confirm you want to continue.
Note:
If you continue, activity to array drives and to
non-array drives on the same SCSI bus will be paused.
3
To continue, type y. Otherwise, type n.
While SCSI bus activity is paused, the server beeps to remind you to
replace the drive and resume activity. When you have replaced the
drive, resume SCSI bus activity by pressing any key at the Adminis-
trator utility screen.
