Vxrootmirror problem

[Lexxx]

I would to seek your help how to mirror this.
I have disk below ....
# vxdisk list
DEVICE TYPE DISK GROUP STATUS
c0t6d0 simple rootdisk01 rootdg online
c2t6d0 simple rootdisk02 rootdg online
#
i checked vxprint and it shows its not mirrored i mean the volumes does not show any rootdisk02.
# vxprint -g rootdg
TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0
dg rootdg rootdg - - - - - -

dm rootdisk01 c0t6d0 - 71681248 - - - -
dm rootdisk02 c2t6d0 - 71683264 - - - -

v homevol fsgen ENABLED 693856 - ACTIVE - -
pl homevol-01 homevol ENABLED 693856 - ACTIVE - -

pl home1vol-01 home1vol ENABLED 4096000 - ACTIVE - -
sd rootdisk01-05 home1vol-01 ENABLED 4096000 0 - - -

I tried vxdiskadm but gives me error
The disk device c2t6d0 appears to have already been initialized
for vxvm use on the system "loopback".

hi
your disk is defined is volume gorup rootdg but non of the volumes are mirrorred . you can either remove it from rootdg by

vxdg -g rootdg rmdisk c2t6d00

or mirror each volume by vxassist

vxassist -g rootdg mirror c2t6d0 ( as fas as remember the command )

The vxassist worked with all volumes except the rootvol i encountered the error...
anything missed? I need also to test after mirroring if i can boot with it c2t6d0.

twsmp7:/root#vxassist -b -g rootdg mirror rootvol
twsmp7:/root#vxbootsetup: ERROR: Disk rootdisk02 (c2t6d0) priv offset = 128, S/B 2144
vxvm:vxassist: ERROR: Could not setup boot partition for new root mirror(s)

See below vxprint results

You can try to vxrootmir -a
but it would work only when disk is not linked with any dg
vxdg -g rootdg rmdisk c2t6d00

Then just give
vxrootmirr -a

Hope this help !!!

Hi Lexxx,

remove the c2t6d0 from your root disk group.

# vxdg -g rootdg rmdisk rootdisk02=c2t6d0

# /etc/vx/bin/vxdisksetup -iB c2t6d0

# vxdg -g rootdg adddisk rootdisk02=c2t6d0

# vxdiskadm
---
Select an operation to perform: 5
--
At the prompt below, supply the name of the disk containing the volumes to be mirrored.

Enter disk name: [,list,q,?] rootdisk01

The rootdisk01 is the root disk, an empty destination disk is required to mirror the root disk.

Enter an empty destination disk: [,list,q,?] rootdisk02

Note: This operation can take a long time to complete.

Continue with operation? [y,n,q,?] (default: y)
---
# vxvmboot -v /dev/rdsk/c2t6d0

check both disks
# lifls -l /dev/rdsk/c2t6d0
# lifls -l /dev/rdsk/c0t6d0
Check mirror conf
# vxprint -g rootdg

Regards,
Robert-Jan
