boot disk question

golfnut — Wed, 09 Feb 2005 06:03:33 GMT

Below is the output from my system.

Does this mean the second disk c2t6 was created with a pvcreate -B option and mkboot to place boot utilities etc..
How can i find out if the second disk is bootable?

thanks

bash-2.05# setboot
Primary bootpath : 0/0/2/0.6.0
Alternate bootpath : 0/0/2/1.6.0

Autoboot is ON (enabled)
Autosearch is ON (enabled)

Yes, check if your / stand and swap are on both disks

# lvlnboot -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c1t2d0 (0/0/1/1.2.0) -- Boot Disk
/dev/dsk/c2t2d0 (0/0/2/0.2.0) -- Boot Disk
Boot: lvol1 on: /dev/dsk/c1t2d0
/dev/dsk/c2t2d0
Root: lvol3 on: /dev/dsk/c1t2d0
/dev/dsk/c2t2d0
Swap: lvol2 on: /dev/dsk/c1t2d0
/dev/dsk/c2t2d0
Dump: lvol2 on: /dev/dsk/c1t2d0, 0

On another subject - are you running bash as root's shell? This is a no-no. You're going to end up being unable to boot into single user mode someday when you really, really need to.

Thanks..

can i just do a mkboot /dev/rdsk/c2t6d0
and place boot utilities.

The disk is already in the vg00 vg.

or will i have to remove the disk with vgreduce and then add it back in after doing a pvcreate -B

thanks
