Hi bartus11

Thanks for the advice & reply also. But we dont have third disk for live upgrade, in our case s0 is having full disk space assign to it in zfs root pool.. So could you help us by providing the command to detach the mirrored root pool as well as if patching get fails how to boot from detached mirror root pool. As we are bit new to ZFS. If same thing need to be done on UFS then we are well aware of detaching the SVM & booting the disk from second mirror.

Thanks

volunroot(8)						      System Manager's Manual						      volunroot(8)

NAME
volunroot - Remove Logical Storage Manager hooks for rootable volumes SYNOPSIS
/usr/sbin/volunroot [-a | -A] OPTIONS
Specifies that all volumes on the system disk be converted back to UNIX disk partitions, not just the root and swap volumes, rootvol and swapvol. Forces removal of the private region unless it is the last one in the system. DESCRIPTION
The volunroot script can be used to restore the accessibility of the root, swap, and other file systems on the boot disk directly through disk partitions instead of through volume devices. The script also removes other changes that were made to enable booting of the system from the root volume, so that the system will boot with no dependency on the Logical Storage Manager. When used with no options, volunroot affects only the root and swap volumes, rootvol and swapvol. For volunroot to work properly, only one plex must exist for each of the affected volumes. This plex must be the one created by volrootmir or the original plex created when the root disk was encapsulated. This ensures that the underlying subdisks will have equivalent partitions defined for them on the disk. If these conditions are not met, the volunroot operation fails and none of the volumes are converted to disk partitions. The unwanted plexes can be removed using either voledit or volplex. SEE ALSO
