How to find out which disk is used when system booted

We have rootdisk and rootmirror in rootdg. Is there a way to identify, which disk the OS is loaded from ?

Re: How to find out which disk is used when system booted

Hi,

If it is LVM use the below command.

#echo "bootdev/X" | adb /stand/vmunix /dev/kmem
bootdev:
bootdev: 1F005000

Here the disk is c0t5d0 . You should take the middle three digits(050) to know the disk.
Best wishes,

Ganesh.

"rootdg" indicates that LVM is not in use, but vxvm is.

LVM will report this into syslog at boot time, I assume vxvm will do the same.

Hope this helps!

Torsten.
