Re: In the ADFS disk ENV How do I find my boot disk and verify its mirrored.

1. To determine the boot disk on Tru64,

# consvar -l | grep boot_dev

2. To find out if the root volume was mirrored using LSM,

# volprint -pt

Output similar to the following is displayed:


PL NAME VOLUME KSTATE STATE LENGTH LAYOUT NCOL/WID MODE

pl rootvol-01 rootvol ENABLED ACTIVE 262144 CONCAT - RW
pl rootvol-02 rootvol ENABLED ACTIVE 262144 CONCAT - RW
pl swapvol-01 swapvol ENABLED ACTIVE 333824 CONCAT - RW
pl swapvol-02 swapvol ENABLED ACTIVE 333824 CONCAT - RW
pl vol-dsk0g-01 vol-dsk0g ENABLED ACTIVE 1450796 CONCAT - RW
pl vol-dsk0g-02 vol-dsk0g ENABLED ACTIVE 1450796 CONCAT - RW

Following best practice at HP Tru64 website has all the details about mirroring boot disk,

many times written in several conferences......

# ls -la /etc/fdmns/root_domain

if device is /dev/vol/* LSM. In this case:

# volprint -Aht

Ashan,

And of course, you can mirror your boot disk at the hardware layer too. You'd need to be able to trace your boot device back to whatever storage system you're using and check there. (I say this just to make sure you know there is more than one way to mirror root.)

Another trick for your bag of tricks is "sizer -r" to display the root device. This should correspond with the consvar output and the contents of the /etc/fdmns/root_domain link.
