Note:

When you run fixboot.exe on the diskette, the diskette remains bootable
unless you reformat it; if you later erase files on the diskette, you do not
need to run fixboot.exe again.

5. Remove the diskette from the appropriate diskette drive. Label the diskette

appropriately and keep it in a safe place.

You can create additional copies of the diskette using the above procedure for each
new copy.

Note:

If you change the backup location or logon settings using the Disaster
Recovery Settings page, you must rebuild the PSM recovery diskettes for
that node to reflect the new settings for that node.

Static IP addressing

If you do not have a DHCP server on your network, and you must access a backup
image that is accessible only through the network (for example, no backup image is
located on the maintenance partition [D: drive] of the node to be recovered), then
you must configure the recovery diskette so that it will use a static IP address and
subnet mask when accessing the network.

On the PSM recovery diskette, edit the file a:\net_sets.bat. Set the IPAddress and
SubnetMask environment variables as follows:

1. Uncomment the two lines that begin with

rem

(comment lines) by removing the

rem

from the beginning of both lines.

2. For each line, what follows the equals sign (=) is an IP address expressed as a

set of four space-separated numbers (an IP address without the dots [.]).
Change the SubnetMask value to match the subnet mask that your network
uses. Change the IPAddress value to match the IP address that 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

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-ROM as described in Chapter 9, “Using the
Recovery and Supplementary CD-ROMs” on page 111 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).
