IBM 201 manual If you have multiple 10/100 Ethernet adapters, Restoring the system drive

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 recovery diskette, edit the file a:\net_sets.bat. Near the top of this file are two lines that begin with rem (comment lines) that, when you uncomment them, set the IPAddress and SubnetMask environment variables. Change these lines as follows:

1.Uncomment both lines by removing 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 your network uses. Change the IPAddress value to match the IP address you want to assign to the NAS 200, 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 NAS 200 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

If you have multiple 10/100 Ethernet adapters

If your NAS 200 has more than one 10/100 Ethernet adapter, then you must configure the recovery diskette to select the 10/100 Ethernet adapter to be used for disaster recovery over the network (the network over which the network drive(s) containing backup image(s) can be accessed). On the 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 NAS 200) in which the desired 10/100 Ethernet adapter is installed:

v0x0009 for PCI slot 1

v0x000a for PCI slot 2

v0x0026 for PCI slot 4

v0x0027 for PCI slot 5

Restoring the system drive

If you need to restore the system drive from a backup image created via the PSM Disaster Recovery panel as described above, you must use a recovery diskette created via the Disaster Recovery panel. If you did not create a recovery diskette then you must use the Recovery CD as described in “Using the Recovery Enablement Diskette and Recovery CD Set” on page 77 to restore the system drive to its original (factory) configuration.

To restore the system drive:

1.Set the write-protect tab of the recovery diskette to the write-protect position. (This is a protection feature to prevent accidental initiation of the recovery process (by booting the NAS 200 with the recovery diskette in the diskette drive).
