Ignite across multiple disks, leaving original disks alone.

[Sheriff Andy]

Hello,

I will try to be as clear as possible. We have an L1000 server.

We had 2 36GB drives (originals), but a couple weeks ago we added 2 more 36GB drives (added disks). This is what I want to do. Ignite to the (added disks) as such;

FS Size(MB) Pri Disk Mirror disk
/ 800 Added Disk1 Original Disk1
/stand 800 Added Disk1 Original Disk1
/var 10000 Added Disk2 Original Disk2
/usr 10000 Added Disk1 Original Disk1
/tmp 3000 Added Disk2 Original Disk2
/opt 10000 Added Disk1 Original Disk1
/home 500 Added Disk2 Original Disk2 SWAP 5000 Added Disk1 Original Disk1

I plan on mirroring the disks as soon as the OS is up and available. Will there be a problem with this at bootup? Since I have the Original disk left as is, until the OS is online (then I will mirror). My concern is that the OS is going to see 2 boot disks (added disk & original disk) and get confused.

Thx in advance,
Andy

I have the same issue.

In the filesystems tab on the Ignite boot menu, there is a place to define which disks you want a part of VG00. The other disk will not be touched.

Make sure that you choose the advanced option when you boot off of the tape/ignite server. If you are using make_tape_recovery, use the -I option to automatically boot the system to an Ignite menu.

Josiah,

Thanks for your response. I assume that your method worked quite well?

Was that make_tape_recovery option an I as in India or l as in Lewis?

capitol I(like India)

From 1M manpage for make_tape_recovery:

-I Cause the system recovery process to be interactive when booting from the tape. By default, when the systems boots from the recovery tape it will give you 10 seconds to interrupt the automatic recovery process in order to interactively make modifications. When the -I option is specified, booting from the tape will always present the interactive menus. Using this option is useful when you know you need to make configuration changes during the recovery, and may also help prevent an accidental system recovery in case you boot from a recovery tape by mistake.
