Full Discussion: Mksysb restoration
Operating Systems AIX Mksysb restoration Post 302976810 by rbatte1 on Wednesday 6th of July 2016 11:58:01 AM

Another thing I could suggest would be that LV mirrors will need to be respected too. I fell over that when restoring to a server with a HUGE single disk protected externally. I can't remember if it was local hardware RAID or a SAN.

The problem is that the mirrors have to go on separate PVs (as far as the OS knows) and we just had one. There was an unsupported adjustment that I had to do to the volume group definition file (created by mkszfile) before running mksysb but once it's written you are a bit stuck.

I have seen it done by DR provider professionals where they copy the image into a NIM server and adjust it, but that's just me witnessing it rather that knowing what they did.

Is your DR site and equipment owned by your company or is it rented time from a DR specialist company?

I must say that using tapes for such a large rootvg seems a little odd. Is there not a DVD-RAM drive available?



Kind regards,
Robin

vxr5check

vxr5check(1M)															     vxr5check(1M)

NAME

       vxr5check - verify RAID-5 volume parity

SYNOPSIS

       /etc/vx/bin/vxr5check [-i | -v] [-g diskgroup] volume

DESCRIPTION

       The vxr5check utility compares the parity of each stripe of a RAID-5 volume specified by volume.  vxr5check reads the data for each stripe,
       generates the parity for this stripe, and compares this parity with the existing parity.

       vxr5check can be run against the entire RAID-5 volume, or incrementally on RAID-5 stripe boundaries, by specifying the -i option.

OPTIONS

       -g diskgroup
		 Specifies the Veritas Volume Manager (VxVM) disk group name for the RAID-5 volume name for verification.  If this option  is  not
		 specified, the default disk group is determined using the rules given in the vxdg(1M) manual page.

       -i	 Verifies the RAID-5 volume incrementally per stripes.	If a parity mismatch is found, that stripe location is displayed.

       -v	 Verbose output for the incremental vxr5check verification.  The verbose option outputs each stripe number that is being verified.

OUTPUT FORMAT

       In  verbose  mode and incremental mode, summary reports for each stripe of the RAID-5 volume are printed in output records.  If an error is
       returned for a stripe, then an error message and stripe number are displayed.  In non-verbose mode, if an error is returned, an error  mes-
       sage is displayed.

       If a parity mismatch error is determined on a stripe, vxr5check exits on that stripe and does not continue for the remaining stripes in the
       RAID-5 volume.

FILES

       /usr/lib/vxvm/bin/vxr5vrfy    The utility that vxr5check calls to perform RAID-5 parity verification operations for  the  specified  RAID-5
				     volume.

EXIT CODES

       The  vxr5check  utility exits with a non-zero status if the attempted operation fails.  A non-zero exit code is not a complete indicator of
       the problems encountered, but rather denotes the first condition that prevented further execution of the utility.

       See vxintro(1M) for a list of standard exit codes.

NOTES

       Do not run vxr5check on a volume that is in degraded mode.
