exit 0. This causes a reboot from the C side. To reboot from the A or B side or from *NWSSTG, you should vary off the system instead of exiting the shell.
36.2.1. Special Considerations for Accessing the SCSI Utilities from Rescue Mode
- Boot from the CD-ROM with the
linux rescue askmethodcommand. This allows you to manually select NFS as the source of your rescue media instead of defaulting to the CD-ROM drive.
- Copy the first installation disc onto a file system of another Linux system.
- Make this copy of the installation disc available through NFS or FTP.
- Vary off or power down the system 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
boot.imgon your IFS (from step 1, above).
- Make sure the installation disc is not in your DVD drive.
- IPL the Linux system.
- Follow the prompts as described in Section 36.2, “Rescue Mode on Power Systems servers”. An additional prompt for the installation source appears. Select NFS or FTP (as appropriate) and complete the following network configuration screen.
- When the Linux system has booted into rescue mode, the CD-ROM drive is available for use and you can mount the driver media to access the SCSI utilities.
