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.
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 non-array drives will
be paused, as well as activity to array drives.
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.
