REMOVING OLD DISKS

[Archie Ogden]

I need to remove old unsupported disks from our
k360 running 10.20.They had the root volume group on them, but I have moved root using LVM. The disks are all now marked UNUSED.When I disconnect them from the system and reboot, the boot process just loops.
Do I need to do anything else before disconnecting thse disks ?

Did you re-set your primary (and alternate) boot paths?

Hi Archie,

I recommend you to do a move on new root disks with ignite-ux.Create a recovery tape with make_tape_recovery command. Shutdown your system and replace your boot disks. Then boot from the tape and recover your system on the new disk. If you have mirrored your root disk, you must recreate your mirror.
You have also the ability to do a interactive recovery from the tape. So you can resize partitions (increase/decrease) or change the filesystem from hfs to vxfs etc. etc. . I think that is the best way to do this.

1.Yes I changed the Pri and Alt boot.
2.I cannot run the make_tape_recovery interactive as I only have a character based console, any way I have already moved root and can boot from the new PRI and ALT.

Archie,

Did you change the device file for the root disk in /stand/bootconf?

HI:

Regardless of the type of console you have, you *can* run an interactive Ignite recovery session. I presume that you have a current Ignite recovery tape. Boot your server from the tape by selecting the tape as your boot path.

Regards!

Hi Archie,

It is like James and I said. The Interactive GUI from ignite is a ASCII GUI. So no need for graphical terminal.
I guess your orignial disk is always in your system. So boot from this disk and create a ignite tape.
# make_tape_recovery -vI -x inc_entire=vg00 -a /dev/rmt/0mn

After you have done this boot from this tape. The boot will automatically start in interactive mode. Then you can change the disk where this system should be recovered.
After you made your changes start the recovery with the *Go* option.
Then go and get a big mug of coffee. After 30-60 min. (depends of your system) your recovery is finished. And you have a runnable system on a *NEW* disk.

I see in my reply the *I* looks like a *l* (el) but it is a *i* (upper case).

Archie,

While I agree that the Ignite process is the more standard, and more foolproof, way to go, I would like to see, since you say you are able to boot off the new disk, just which piece of the puzzle we might be missing.

When you say you have booted off the new root volume, how did you accomplish this without the boot process looping?
