Ignite disk selection to diffrent hardware

Larry Basford — Wed, 07 Feb 2007 10:19:57 GMT

When I Ignite an N4000 from an L2000
The boot disk is /dev/dsk/c2t0d0 (0/0/2/0.0.0) which does not exist.

Ignite always selects my EMC VCM database disk 000 to install to
1/12/0/0.116.2.6.0.0.0 LVM vg00 45 MB

How can I make it default to my internal disk ?
Or make it not see my EMC VCM database disk?

Larry,

Do the advanced installation, you should have a screen come up that allows you to pick which disk to use

Also, on the basics tab, select the additional button and set clone to different hardware = True

Larry,
are you running the ignite interactive (-i). This should give you the option on where to install. Is all your other hardware between the two server types compatible?

Just a side note.

Be carefull cloning from one HW platform to another. Although the L/rp54xx series is funtionally close to an N/rp74xx series you may run into issues with different drivers required due to some minor HW differences.

Cloning same HW is good, attempting one to another is AYOR ( At Your Own Risk )

ALL good answers but not to the question asked.
How can I make it default to my internal disk ? or NOT see the EMC disks.
I know how to change it I just don't want to.
This is for local High Availibility failover.
The N ignites fine as long as you have the drivers loaded for either hardware. like FC card differences.

unplug/disable the emc disks before igniting is about the only I know of.

Larry,

I did some research - the ignite installation configuration manual chapter 7 has instructions to configure the defaults for a client in /var/opt/ignite/clients/ox...

It is pages 162 and 163

It looks like I might make a make_tape_recovery with a -p to preview
Then change the /var/opt/ignite/recovery/2007-02-07,21:25/system_cfg
from init _hp_root_disk="0/0/2/0.0.0"
to init _hp_root_disk="0/0/2/0.6.0"
then again with -r to resume
And when it loads on the N4000 it should find the disk.

I guess I'll have to try it.
