Hello Folk's,

I have an hpux box which has vxvm root disk, I have a primary disk which is working fine, my secondary needs to be replaced, i have followed that steps which are required to do the root mirror, but looks like the its not in right way.


cphppts2 # vxvmboot -v /dev/rdsk/c2t0d0   <<=== secondary disk after mirrioring

VxVM vxrootmir INFO V-5-2-1616 00:22: Disk c2t0d0 is now a mirrored root disk


from the above logs, the issue is it should have boot/root/swap but the these volumes are not mirrored in-order,

the system is unable to boot from alternate disk as its not able to find /stand/vmunix.

Please let me know if there is way to resolve this?

Thanks & Regards,
Govinda.
