This update provides new adapter firmware (FW) for the following adapter:
The levels contained in this update are:
Adapter Firmware Level | Description |
4.20.18 |
|
This update will disrupt adapter operations. The update should be done with no user activity on the system.
Remove cables from the adapter noting which cable goes to which connector so they can be reconnected in exactly the same positions.
Remove the battery backed-up cache card from the base card by
removing the 8 screws visible when looking at the battery side of
the adapter. Carefully separate the 2 cards by rocking the cache
card near the connectors joining the 2 cards. Do not disconnect the
battery wires because there may be valid data in the the battery
backed-up cache card.
Install the battery backed-up cache card on the replacement base
card being careful to position the battery wires so they do not
interfere with the mounting screws or the PCI connector. Reinstall
the adapter and cables in the system.
Before you install the microcode, it is important
to determine the Microcode level of the adapter when
you install it in the target system. Use the following
instructions to read the Loadable Microcode Level
stored in the adapter's non-volatile memory.
1) List the PCI Raid adapters installed in the
system by typing:
lsdev -C | grep scraid
Note the device names of all PCI 4-Channel PCI Ultra3
SCSI Raid Adapters installed. The adapter device name
will be scraidX,where X is 0,1, or some other number.
Identify the name of the card you just installed.
2) To check the current microcode level for the
adapter enter the following command
lscfg -vl scraidX
Where X is the number of the card you just installed.
The Command will produce output similar to
DEVICE LOCATION DESCRIPTION
scraid0 20-58 PCI 4-Channel Ultra3 SCSI RAID Adapter
Part Number.................09P1521
EC Level....................0H10522
Serial Number...............00000001
FRU Number..................37L6892
Manufacturer................IBM000
Displayable Message.........UL3RAID
Diagnostic Level............03
Device Driver Level.........03
Loadable Microcode Level....4.20.01
ROS Level and ID............4.00.26
Device Specific.(YL)........P2-I9
If the FRU Number is 37L6892 and Loadable Microcode
Level is different than 4.20.18 as it is in the above
case (4.20.01) then you should update the microcode.
The Firmware Update Commands:
FLASH the adapter EEPROM using one of the 2
following commands:
- If the loadable microcode level listed previously
is below 4.20.18 then type:
diag -c -d scraidX -T"download"
Where X is the numerical character denoting the logical ID
of the SCSI RAID adapter you identified previously.
-If the loadable microcode level listed previously
is above 4.20.18 then type:
diag -c -d scraidX -T"download -P"
This will cause 4.20.18 load even if a higher level from
some other application is on the card.
You should receive a confirmation that microcode has
been updated. If you do not then make sure the adapter
is NOT in use and repeat step 8.
Verifying the Update
To verify that the correct level of microcode, 4.20.18,
is on the adapter type:
lscfg -vl scraidX
Where X is the numeric character denoting the logical
ID of the SCSI RAID
adapter you identified previously.
RESTORING THE ARRAY CONFIGURATION ON THE NEW ADAPTER
After downloading the adapter follow the procedure in the chapter:
"Replacing the PCI 4-Channel Ultra3 SCSI RAID Adapter" in the
adapter REFERENCE GUIDE, SA23-1239-00 which is summarized below:
Attention:If the adapter being replaced experienced an abrupt
failure, there may be valid data in the adapter's non volatile
write cache.
If an existing disk array configuration will be imported from the
attached drives, then the write cache card from the adapter being
replaced should be used with the new adapter. This will ensure any
data which may exist in the non-volatile write cache module is
correctly written to the attached disk drives.
A configuration conflict may result when a PCI 4-Channel Ultra3 SCSI
RAID Adapter within a configured system is replaced (possibly
due to a defective adapter). The configuration stored on the
adapter may be out of sync with the configuration stored on the
drives. The configuration can be restored by synchronizing the
adapter configuration with the drive configuration. This can be
accomplished using the ACCEPT CONFIGURATION ON DRIVES option under
PDAM RECOVERY OPTIONS. PDAM is the PCI SCSI Disk Array Manager
under SMIT.
Use the following to do this:
1. Start PDAM by entering the following command:
smit pdam
2.Select the RECOVERY OPTIONS option.
3. Select RESOLVE PCI SCSI RAID ADAPTER CONFIGURATION option.
4. Select ACCEPT CONFIGURATION ON DRIVES option.
5. Select the adapter that was replaced.
NOTE: following an Accept Configuration on Drives option, the PCI
4-Channel Ultra3 SCSI RAID Adapter will automatically perform a
Consistency Check with Auto-Repair on all redundant level RAID
arrays. Progress of the Consistency Check can be monitored using
the list PCI SCSI Disk Arays option of PDAM.
