5-50 Installing the Operating System with Express Setup

Notes

The following explains general notes on HostRAID:
<SCSI HostRAID>
Only a hard disk drive can be connected to a channel with which HostRAID is enabled
through SCSI BIOS.
To connect a device other than a hard disk drive, disable HostRAID and use it as the
standard SCSI.
If you replace a hard disk drive being used with HostRAID, let 60 seconds or more pass
after removing the hard disk drive, and then install a new hard disk drive.
If the interval is too short, an unexpected event may occur. (You should install a new hard
disk drive after confirming the removal of the old hard disk drive on the ASMBE
window.)
After rebuilding by using hot spare, do the rebuilding again to make the installation
positions of hard disk drives and the configuration of an array using the disks same as
those before the configuration of the array. Without the operation, the boot priority may be
changed. The priority can be changed by the SCSISelect Utility.
The timeout message below may be recorded into the event log if I/O operation is delayed
while HostRAID is running with a high load applied. However, HostRAID internal
processing retries the I/O processing, and the delay does not influence AP and system
operations.
Event source: a320raid.sys
Event ID:
Description: The device \Device\Scsi\a320raid* did not respond within timeout period.
When Hot Spare Rebuild is performed, please perform Rebuild again to become the
original hard disk drive mounting position and the same position. If this work is not done,
a boot priority may change. A boot priority can be changed in BIOS.
