Operating Systems AIX How to manually -re-attach AIX lv's to a mirror? Post 303028772 by mrmurdock on Monday 14th of January 2019 04:30:51 PM

Thank you.
I may not be in as bad of shape as I think i am. lslv -l hd2 shows hdisk1 with a 0% in the IN BAND column, which from the man pages sounds like the OS is not writing to the lv anymore.
Code:
# lslv -l hd2
hd2:/usr
PV                COPIES        IN BAND       DISTRIBUTION  
hdisk1            040:000:000   0%            001:039:000:000:000 
hdisk0            040:000:000   100%          000:000:040:000:000

Code:
 synclvodm  rootvg

returns with no errors.
It almost seems like i could just pull hdisk1 out and be ok at this point. Its a gut wrenching decision (probably wont do it though). I have re-ran bosboot -ad /dev/hdisk0 and made sure my bootlist lists hdisk0 first. If there was trouble as far as os problems, I would expect my OS by now to be choking and dying if I had any filesystem access, os command errors, accessing hdisk0, however, its still running fine (running DB2 and Informix developement DB's).

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

NAME
volreattach - Reattaches disk drives that have once again become accessible SYNOPSIS
/usr/sbin/volreattach [-rb] [accessname...] /usr/sbin/volreattach -c accessname OPTIONS
The volreattach utility has the following options: Calls the volrecover utility to attempt to recover stale plexes of any volumes on the failed disk. Performs the reattach operation in the background. Checks whether a reattach is possible. No operation is performed, but the name of the disk group and disk media name at which the disk can be reattached is displayed. DESCRIPTION
The volreattach utility attempts to reattach disks using the same disk group and media names they had before detachment. This operation may be necessary if a disk has a transient failure, or if some disk drivers are unloaded or unloadable when the Logical Storage Manager is started, causing disks to enter the failed state. If the problem is fixed, the volreattach command can be used to reattach the disks without plexes being flagged as stale, as long as the reattach happens before any volumes on the disk are started. The volreattach command is called from the voldiskadm menus as part of disk recovery. The volreattach utility tries to find a disk with a disk group and disk ID matching that of the disk(s) being reattached. If the matching disk is found, the reattach operation may still fail if the original cause (or some other cause) for the disk failure still exists. EXIT CODES
A zero exit status is returned if it is possible to perform a reattach. Otherwise, non-zero is returned. SEE ALSO
