NEVER SWAP FIXED DISK WITHIN A CONFIGURED RAID ARRAY to
troubleshoot drive problems, such as DDD. Swapping drives which contain customer
data will almost always result in LOST DATA
NOTE: With the ServeRaid adapter, ServeRaid Onboard Controller
and ServeRaid II Adapter, SYNCHRONIZATION IS REQUIRED to
ensure the PARITY ACCURATELY REFLECTS THE DATA.
IF Synchronization or Data Scrubbing is performed on
an ARRAY that was NEVER PREVIOUSLY SYNCHRONIZED, then
any MEDIA DEFECTS FOUND that REQUIRE RAID RECONSTRUCTION
may be rebuilt using INCORRECT PARITY which MAY RESULT IN
DATA LOSS.
November-1997
Before installing software or data for the first time on an
IBM PC Server RAID system, the following must be performed:
Note (1 = The Firmware/BIOS diskette 2.30 contains the BIOS flash
2.30.04 as well as the Firmware flashes.
NOTE: These Firmware and BIOS versions are to date at the time
this document was released. Firmware and BIOS levels are
subject to change over time. Always check for the latest BIOS
and Firmware utility on the IBM Website URL:
http://www.us.pc.ibm.com/files.html
NOTE: Be sure that the latest version of the corresponding
RAID utility diskette is used to ensure compatibility with
the latest Firmware and BIOS on the corresponding adapter.
NOTE: Synchronization is done automatically when initializing
RAID 5 logical drives on the following adapters:
NOTE: Data Scrubbing of the drives may be accomplished
one of two ways on the following adapters:
NOTE: See the matrix of utilities vs. adapters vs.
Network Operating Systems in the White Paper,
'Using IBM RAID Adapters to Avoid Data Loss'.

Click on 'Search' at the top of the page and use 'White Paper' as Keywords.
NOTE: 'Data Scrubbing' runs automatically in the background
on the ServeRAID II Adapter. The Firmware of the
adapter must be at 2.30.04 or higher to include this
feature.

NOTE: Use the 'IBM PC ServeRAID Synch Verify Update Diskette'
V-1.10 or higher to determine the status of any RAID arrays
on the ServeRAID adapter ONLY. Be sure to read the README
file prior to executing any programs on the diskette.
