Using drd unrehost to review contents of EFI/HPUX/SYSINFO.TXT

If you want to review the contents of the system information file in the EFI partition, you can use the

drd unrehost command to copy it to a file system location you specify and remove it from the EFI

partition. When you are satisfied with the contents, execute the drd rehost command again to

copy it back to the EFI partition.

The following command copies /EFI/HPUX/SYSINFO.TXT to

/var/opt/drd/tmp/file_to_review and removes it from the EFI partition:

# drd unrehost –f /var/opt/drd/tmp/file_to_review

When you are satisfied with the file, you need to rerun the drd rehost command to return the file

to the EFI partition of the inactive image:

# drd rehost –f /var/opt/drd/tmp/file_to_review

Booting the image with SYSINFO.TXT on the target system

You need to use your SAN software to unpresent the SAN LUN from the source system and present it

to the target system. The techniques for doing this are specific to the SAN software you are using.

If the target system is already booted on another disk or SAN LUN, you can use setboot to set the

primary bootpath to the new LUN. If not, you can interrupt the boot process to choose the new LUN,

identifying it by the presence of SYSINFO.TXT in the /EFI/HPUX directory. Alternatively, you can

use one of the techniques mentioned below for Integrity VMs or Blades.

During the boot, the auto_parms(1M) enhancements provided by PHCO_36525 or PHCO_38232

(or superseding patches) will process /EFI/HPUX/SYSINFO.TXT.
