Using make_recovery tape

[Chris Zimo]

Just a few questions about restoring from a make_recovery tape. On my system I am replacing all of my old 2gb disk drives with new 18gb disk drives. I would like to restore my OS from my make_recovery tape, and I plan on restoring my other volume groups (excluding vg00) from my fbackup tape when my OS is restored to the new disks. The man pages for make_recovery states if the disks on the system have been changed, the install process can detect that the hardware is different, and starts up the install user interface to allow changes to the configuration. I would like to eliminate any operator intervention if possible when booting my system from the igninte tape. Is it possible to prepare for this when creating the make_recovery tape from my old disks? I am also concerned with the files /etc/fstab, /etc/lvmtab, /etc/ioconfig. How should I handle these files, and are there other files I should be concerned with?

Your /etc/fstab will remain unchanged unless you plan on creating a new filesystem... or if you have not used lvm to partition your disks.

Your /etc/lvmtab and /etc/ioconfig will need modification if you add disks to new slots (or change scsi id), thus you need to interact to select a different hw path/dev file for your boot device.

The best way to do it would be through a golden image with make_sys_image and boot each individual client with boot_sys running the GUI on the ignite server. However, if there is a different boot image per server this will require lots of space.

You can control each booting client easier by modifying their entry.

Other files to be concerned with are mac addresses of lan cards.. particularly the hp100baseT.conf file.

You need to make sure your image is created with inc_entire=vg00 etc..

DLKMs will not work either (still wondering what my call status on that is?)

Remember ignite is a recovery utility and not a backup utility... as you seem to be paying caution to.

Check your setboot and lvlnboot -v settings after install.

Later,

hi Chris,

Maybe this ignite faq will help,

Here is the ignite ux admin guide,

Hope this helps.

Hi Chris,

Change the new Disk with the SCSI ID of the old disk. And then start the recovery. Since your present OS is on 2GB Disk, I assume that you are having more than one disk in VG00. You just select the Hardware address of the new Disk where the OS will go. After that it will do everything in auto mode.

After reboot just check the lvlnboot -v and strings /etc/lvmtab.

Bill,
Thank you for your reply. Just a few more questions.

I ran make_recovery -p to see what exactly is storing off to tape. I could be wrong, but it looks to me like the ignite will recreate, but not restore, all of the original volume groups. Is this a correct statement? My current system has 17 2gb disk drives with 6 volume groups. The system will be reconfigured with 3 18gb disk drives and only 3 volume groups. How will this impact my restore from the igninte tape?

Also I am not exactly up to speed with "golden image". Could you please shed some more light onto this topic.

Thanks in advance for the help.

Hi Chris,

Chapter 2 of the ignite UX admin guide (posted as second link above discusses the golden image concept and appendix A of the same outlines the step involved in creating a golden image,
