Change the IPAddress value to match the IP address you want to assign to the
node, during the recovery operation. Do not insert dots between the numbers
(octets) in either value.
As an example, here is how the lines would look for a node using IP address
192.168.1.200, and subnet mask 255.255.255.0:
set SubnetMask=255 255 255 0
set IPAddress=192 168 1 200
If you later want to reconfigure the recovery diskette to use DHCP to obtain an IP
address instead of static IP addressing, you must reinsert
rem in front of the
SubnetMask and IPAddress lines to disable static IP addressing, as follows (based
on the previous example):
REM set SubnetMask=255 255 255 0
REM set IPAddress=192 168 1 200
Specifying multiple 10/100 Ethernet adapters
If the Model 326 has more than one 10/100 Ethernet adapter (per node), then you
must configure the PSM recovery diskette to target the 10/100 Ethernet adapter to
be used for disaster recovery over the network. On the PSM recovery diskette, edit
the file a:\net_sets.bat, and add the following line:
set SLOT= slotvalue
where slotvalue is one of the following, depending on the PCI slot (on the rear of
the node) in which the targeted 10/100 Ethernet adapter is installed:
0x0027 For the integrated Ethernet adapter
0x0001 For PCI slot 1
0x0022 For PCI slot 2
0x0023 For PCI slot 3
0x0044 For PCI slot 4
0x0045 For PCI slot 5
Restoring the system drive using the PSM recovery diskette
To restore the system drive from a backup image created through the PSM Disaster
Recovery panel as described above, you must use a PSM recovery diskette created
through the Disaster Recovery panel. If you did not create a PSM recovery diskette,
you must use the Recovery CD as described in “Chapter 9. Using the Recovery and
Supplementary CDs” on page 123 to restore the system drive to its original (factory)
configuration.
To restore the system drive:
1. Set the write-protection tab of the PSM recovery diskette to the write-protect
position. This prevents accidental initiation of the recovery process (by booting
the node with the PSM recovery diskette in the diskette drive).
2. Insert the PSM recovery diskette in the diskette drive of the node, and restart
the node.
3. The recovery process begins. The PSM recovery diskette software locates the
first backup image it can find, based on the backup locations specified when the
diskette was created. When it locates a backup image, it begins restoring the
system drive from the image. During the restore operation, the hard disk drive
LED (on the front right of the node’s hard disk drive) will flash green or stay
nearly solid green; this indicates write activity to the system volume.
Note: If the hard-disk drive LED stays off for at least 10 minutes since you
restarted the node, then there is a problem with the recovery procedure
