Mirror volumes on a disk
Menu: VolumeManager/Disk/Mirror
This operation can be used to mirror volumes on a disk. These volumes can be be mirrored onto another disk or onto any available disk space. Volumes will not be mirrored if they are already mirrored. Also, volumes that are comprised of more than one subdisk will not be mirrored.
Mirroring volumes from the boot disk will produce a disk that can be used as an alternate boot disk.
At the prompt below, supply the name of the disk containing the volumes to be mirrored.
Enter disk name [,list,q,?] rootmirror
You can choose to mirror volumes from disk rootmirror onto any available disk space, or you can choose to mirror onto a specific disk. To mirror to a specific disk, select the name of that disk. To mirror to any available disk space, select “any”.
Enter destination disk [,list,q,?] (default: any) rootdisk

The requested operation is to mirror all volumes on disk rootmirror in disk group rootdg onto available disk space on disk rootdisk. VxVM NOTICE V-5-2-3650 This operation can take a long time to complete.

Hi Shekar, please try /etc/vx/bin/vxunroot to unencapsulate the rootdg to native paritions. please makes sure the rootdisk has no volumes other than non-systems volumes.

Is that volume disabled before vxunroot? if so please enable and try the command

alternatively, use the traditional process: ( please be cautious, and implement on your own risk)

before proceeding check that you have the original disk partition layout i.e. vtoc ” /etc/vx/reconfig.d/disk.d/vtoc””

— take the system down to failsafe mode/ or cdrom boot and mount the root disk to /a
— modify the /etc/system to comment out “rootdev” and “set vxio ..” entries
— modify /etc/vfstab to use native disk partitions instead of root volumes
— remove root volumes – vxedit -rf rm
— remove the last disk with — vxdg rmdisk
— restore original vtoc to disk. with below command
/etc/vx/bin/vxedvtoc -f /etc/vx/reconfig.d/disk.d/vtoc /dev/rdsk/s2
— boot to single user mode

thanks for your response .
Ok , let me explain , Solairs is mirrored on (svm )booting on native disk , on top of that VVM is installed they are not encap with solaris disk .
vxdisk list
DEVICE TYPE DISK GROUP STATUS
c0t0d0s2 sliced – – error (not VVM control )
c0t1d0s2 sliced – – error( not VVM control )
c1t0d0s2 sliced disk01 rootdg online
– – disk01-m rootdg removed was:c2t0d0s2

Ignore the error in the status for 1st two disk as those are not VVM control

This server is being veritasclustered with another node ,since rootdg is created at the time of installtion of VVM ,so i have only option left now to uninstall Vertitas Volume manager that will remove the rootdg .

1 will this affect the existing VCS between two node
2. Alternatevely ,is there option or commnd to remove rootdg or the last disk in rootdg ?

  Hi Sekhar, Thanks for explaining the setup
  
  >>1 will this affect the existing VCS between two node
  if VCS using any of the VxVM volumes then removing VxVM will affect the VCS
  
  >>> 2. Alternatevely ,is there option or commnd to remove rootdg or the last disk in rootdg ?
  Case a. if you are using vxvm 3.5 and earlier versions, there you shouldn’t remove the rootdg because that is mandatory DG.
  Case b. If you are using vxvm 4.0 and later versions, then simply deport the rootdg and run vxdiskunsetup against the rootdisk which will clear the both public and private regions of the disk.

  Hi Prajwala, I understand your confusion. This post is to help troubleshooting the error “VxVM vxdg ERROR V-5-1-10127 associating disk-media rootdisk with c1t4d0s2: Disk public region is too small” during the rootdisk replacement. and that won’t happens regularly.
  
  I will post the normal procedure little later.
