vxreattach

vxreattach(1M)															    vxreattach(1M)

NAME

       vxreattach - reattach disk drives that have once again become accessible

SYNOPSIS

       /etc/vx/bin/vxreattach [-br ] [accessname...]

       /etc/vx/bin/vxreattach -c accessname

DESCRIPTION

       The vxreattach utility reattaches disks to the disk group they were in and retains the same media name.

       This  operation	may  be  necessary  if	a  disk has a transient failure, or if Veritas Volume Manager (VxVM) starts with some disk drivers
       unloaded and unloadable. Disks then enter the failed state.  If the problem is fixed, vxreattach may be able to reattach the disks  without
       plexes being flagged as stale, as long as the reattach happens before any volumes on the disk are started.

       vxreattach  tries  to find a disk in the same disk group with the same disk ID for the disk(s) to be reattached. The reattach operation may
       fail even after finding the disk with the matching disk ID if the original cause (or some other cause) for the disk failure still exists.

       vxreattach is usually invoked by vxdiskadm when performing disk recovery.  It is not intended to be run directly by an administrator.

OPTIONS

       -b	 Performs the reattach operation in the background.

       -c	 Checks if 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.

       -r	 Tries to recover stale plexes of any volumes on the failed disk.  It does this by calling vxrecover.

EXIT CODES

       A zero exit status is returned if the reattach is performed; non-zero is returned otherwise.

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

EXAMPLES

       Check if reattachment of disk c1t2d0 is possible:

	      /etc/vx/bin/vxreattach -c c1t2d0

       If  reattachment  is  possible, vxreattach returns with an exit status of 0 and displays the disk group name and disk media name.  If reat-
       tachment is not possible, vxreattach returns an exit status of 2 and displays an error.

       Attempt to reattach the disk in the foreground and try to recover stale plexes of any volumes on the disk:

	      /etc/vx/bin/vxreattach -r c1t2d0

       If the reattachment is successful, vxreattach returns an exit status of 0.  Otherwise, if an error occurs, vxreattach  returns  a  non-zero
       exit code as defined on vxintro(1M).

FILES

       /etc/default/vxplex Standard  defaults file that can be used to determine whether FastResync is used when attaching plexes.  See vxplex(1M)
			   for details.
