Special Considerations for Accessing the SCSI Utilities from Rescue Mode

If your LPAR uses Native DASD disks, you may need access to the SCSI utilities from rescue mode. These utilities are located on the driver disc CD. The driver disc CD cannot be mounted from rescue mode unless special steps are taken. These steps are described below.

If you have a second CD-ROM drive assigned to your Linux LPAR, you can mount the driver disc CD in the second drive.

If you have only one CD-ROM drive, you will need to set up an NFS boot, using the following steps:

1. Copy /qopt/red_hat/ppc/iSeries/vmlinux to the IFS of the iSeries system containing your Linux LPAR. You can do this with a command like:

   COPY OBJ ('/qopt/red_hat/ppc/iseries/vmlinux') TODIR('/tmp')

   Note that /tmp can be replaced with any location on your IFS.

2. Copy the first installation disc onto a filesystem of another Linux LPAR or other Linux system.

3. Make this copy of the installation disc available through NFS or FTP.

4. Vary off or power down the LPAR you need to rescue. Set its IPL parameters as instructed for booting the Installation discs in rescue mode, except that the IPL source should point to the copy of vmlinux on your IFS (from step 1, above).

5. Make sure the installation disk is not in your CD-ROM drive.

6. IPL the Linux LPAR.

7. Follow the prompts as decribed in the Section called Using the Installation Disks in Rescue Mode. You will see an additonal prompt for the installation source. Select NFS or FTP (as appropriate) and complete the following network configuration screen.

8. When the Linux LPAR has booted into rescue mode, the CD-ROM drive will be available and you can mount the driver disk to access the SCSI utilities.
