vxevac(1M) vxevac(1M) 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.

vxmirror(1M) vxmirror(1M) NAME
vxmirror - mirror volumes on a disk or control default mirroring SYNOPSIS
/etc/vx/bin/vxmirror [-g diskgroup ] [-d yes|no ] [-t tasktag ] medianame [new_medianame...] /etc/vx/bin/vxmirror [-g diskgroup ] [-d yes|no ] [-t tasktag ] -a [new_medianame...] /etc/vx/bin/vxmirror [-g diskgroup ] [-d yes|no] /etc/vx/bin/vxmirror [-g diskgroup] -D DESCRIPTION
The vxmirror command provides a mechanism to mirror all non-mirrored volumes that are located on a specified disk, to mirror all currently non-mirrored volumes in the specified disk group, or to change or display the current defaults for mirroring. All volumes that have only a single plex (mirror copy), are mirrored by adding an additional plex. Volumes containing subdisks that reside on more than one disk are not mirrored by vxmirror. vxmirror is generally called from the vxdiskadm menus. It is not an interactive command, and after it is called, continues until comple- tion of the operation or until a failure is detected. Note: Generating mirror copies of volumes can take a considerable time to complete. In the first listed form of this command, the disk media name is supplied on the command line to vxmirror. That name is assumed to be the only disk from which volumes are mirrored. In the case of mirroring volumes from a specified disk, only simple single-subdisk volumes are mirrored. In the first and second listed forms of the command, new_medianame... identifies a new disk media name (or set of names). The mirroring operation uses these names as targets on which to allocate the mirrors. An error results if the same disk is specified for both the source and target disk and if no other viable targets are supplied. Hardware-Specifc Note Some environments provide guidelines to optimize the VxVM's interaction with intelligent storage systems. If these guidelines are present, VxVM follows the guidelines when creating volumes or allocating space for volumes. By default, vxmirror only creates mirror volumes that conform with these guidelines. The following options change the behavior of vxmirror: -o override Creates a mirror of the specified volume and ignores any storage-specific guidelines. Overriding the guidelines is not recom- mended as it can result in incompatible objects, or objects that cannot be administered by VxVM. -o verify Verifies that the specified mirror can be created without violating any storage-specific guidelines, but does not create the plex. If any guidelines are violated, vxmirror exits with an error message. Note: These options need a specific license. Without the license, vxmirror ignores the specified option. OPTIONS
-a Mirrors all existing volumes for the specified disk group. -d yes | no Changes the default for subsequent volume creation, depending on the option argument. If yes, then all subsequent volumes cre- ated automatically become mirrored volumes. If no, then mirroring is turned off for future volumes created. -D Displays current default status for mirroring. -g diskgroup Limits operation of the command to the given disk group, as specified by disk group ID or disk group name. The medianame oper- ands are evaluated relative to the given disk group. If this option is not specified, the default disk group is determined using the rules given in the vxdg(1M) manual page. -t tasktag Specifies using a tasktag as the tag for any tasks created to perform the mirror operations. EXAMPLES
The following command mirrors all non-mirrored volumes on disk disk01 to the available space on any other available disk. Subsequent calls to vxassist mirror created volumes by default. /etc/vx/bin/vxmirror -d yes disk01 This command displays the current status of default mirroring. It outputs the string yes if mirroring is currently enabled, or no if mir- roring is not enabled. /etc/vx/bin/vxmirror -D This command mirrors any volumes on disk02 to disk03. /etc/vx/bin/vxmirror disk02 disk03 FILES
/etc/default/vxassist The defaults file for vxassist parameters. SEE ALSO
