NAME

       vxevac - evacuate all volumes from a disk

SYNOPSIS

       /etc/vx/bin/vxevac [-g diskgroup] [-k [-O operation-tag]] [-t tasktag] 
	   medianame [new_medianame...]

       /etc/vx/bin/vxevac [-g diskgroup] [-O operation-tag] [-t tasktag] 
	   commit medianame

       /etc/vx/bin/vxevac [-g diskgroup] [-O operation-tag] [-t tasktag] 
	   rollback medianame

DESCRIPTION

       The  vxevac  utility  moves  subdisks  off  the specified Veritas Volume Manager (VxVM) disk (medianame) to the specified destination disks
       (new_medianame...).  If no new_medianame arguments are specified, any non-volatile, non-reserved disks can be used  as  destination  disks.
       Subdisks that are part of unmirrored striped plexes are moved by moving the entire plex to a new location.

       Note:  This  operation  assumes that there is sufficient space in the disk group for the operation to complete.	If the process runs out of
       space, some of the volumes on the disk may not be evacuated.

       vxevac is usually called from the vxdiskadm menus.

       A medianame argument is an administrative name used to define a disk within a disk group.

       The evacuation of a volume can be committed or rolled back if the -k option is specified. Such an operation is referred to as  a  "tentaive
       move."  In addition, the -O option may be used to define a tag for a given tentative move operation.

KEYWORDS

       commit	 Completes tentative subdisk move operations by removing the source subdisks, and replacing them with the target subdisks.  The -O
		 option can be used to specify an operation tag for the subdisks whose tentative move is to be committed.  If no operation tag	is
		 specified,  the  commit operation is applied to all completed tentative subdisk moves for the specified media.  The commit opera-
		 tion fails if a tentative move or a recovery resynchronization is in progress.

       rollback  Reverses tentative subdisk move operations by removing the target subdisks, and leaving  the  source  subdisks  intact.   The	-O
		 option  can  be used to specify an operation tag for the subdisks whose tentative move is to be rolled back.  If no operation tag
		 is specified, the rollback operation is applied to all completed tentative subdisk moves for the specified media.   The  rollback
		 operation fails if a tentative move or a recovery resynchronization is in progress.

OPTIONS

       -g diskgroup
		 Specifies the disk group for the operation, either by disk group ID or by disk group name.

       -k	 Initiates  a subdisk move while preserving the source subdisks on the original plexes. The source and target subdisks are marked.
		 The tentative move operation can be committed or rolled back at a later time.	If the -O option is used to specify  a	tag,  this
		 tag can be used with the vxtask command to monitor, pause or abort such operations.

       -O operation-tag
		 Specifies  an operation tag that can be used to commit or roll back a completed tentative move operation.  If an operation tag is
		 specified, a task tag is automatically set to the same value. However, setting a task tag does not imply the setting of an opera-
		 tion tag.

       -t tasktag
		 Specifies  an administrative operation to perform by the numeric identifier tasktag.  See the vxtask(1M) manual page for informa-
		 tion on Veritas Volume Manager tasks.
