Rescanning All Channels
This function allows the user to scan all disk channels for new or removed disk drives. The
rescan will temporarily pause all I/O processes (normal operation will resume once rescan
is complete).
If using an InfoStation with the SAF-TE Board installed, the controller will perform a rescan
automatically. With the SAF-TE Board, the controller will detect removed drives almost
immediately; installed drives will be detected after a 3 minute delay (to allow for drives to spin
up).
NOTE: If installing a new drive, wait for the drive to spin up before rescanning the channels.
This will avoid unnecessary delays during the rescan that can cause the operat-
ing system to time-out.
To rescan all channels:
1. Select Utilities Menu from the System Menu and press Enter.
The Utilities Menu should now display (Figure 45).
2. Select Rescan and press Enter.
Pausing I/O
The function allows the user to suspend activity on all device channels used in the controller,
thereby ensuring data integrity on the connected drives and arrays.
CAUTION: Pausing I/O halts active I/O to the host!
To pause I/O:
1. Select Utilities Menu from the System Menu and press Enter.
The Utilities Menu should now display (Figure 45).
