IBM calls this technique "Alternate Disk Install". You install the OS from your NIM server to a spare disk in the machine. There are tons of docs on this at IBM's website.
http://publib.boulder.ibm.com/infoce...v5r3/index.jsp
However, you can NOT use that disk with the different OS without a reboot. Basically you can have both OS versions installed and choose which you boot to but both can't be running at the same time.

I cloned the drive using the DD command.
Using the format command and examining the partitions, all looks the same as the original drive.

I want to increase the size of /tmp by 1GB
I know that the command is
chfs -a size=+1G /tmp
But the rootvg is mirrored and when I do a lsvg -p rootvg, I could see 2 disks.
Will there be any impact if I increase the size of /tmp when the rootvg is mirrored ?
Please advise. (1 Reply)

dgcfgbackup
dgcfgbackup(1M) dgcfgbackup(1M)
NAME
dgcfgbackup - create or update VxVM volume group configuration backup file
SYNOPSIS
/usr/sbin/dgcfgbackup [-f dg_conf_path ] dg_name
DESCRIPTION
The dgcfgbackup command saves the VxVM configuration for a disk group in a default or alternate configuration backup file (see the descrip-
tion of the-f option).
By default, dgcfgbackup is run automatically each time that a VxVM command changes the VxVM configuration. In this case, it always uses
the default configuration backup file. An existing default configuration backup file is renamed with an extension of .old.
Options and Arguments
dg_name Specifies the name of a disk group.
-f dg_conf_path
Saves the configuration using an alternate file name specified by dg_conf_path. If this option is omitted, the default file name
is /etc/vxvmconf/dg_name.conf.
EXIT CODES
dgcfgbackup exits with a zero status on successful completion. An non-zero exit status indicates that errors occurred when information
from the disk group was being accessed.
EXAMPLES
Back up VxVM configuration information for disk group testdg in the default backup file /etc/vxvmconf/testdg.conf:
dgcfgbackup testdg
Back up VxVM configuration information for disk group datadg in the alternate configuration backup file /tmp/datadg.backup:
dgcfgbackup -f /tmp/datadg.backup datadg
NOTES
It is recommended that any alternate configuration backup file be created in the root file system (as is the case with the default path
name). This facilitates disk group recovery during maintenance mode, such as after a system crash.
