When you add a disk to a system that is running VxVM, you need to put the disk under VxVM control so that VxVM can control the space allocation on the disk. Unless you specify a disk group, VxVM places new disks in a default disk group according to the rules given in Rules for determining the default disk group.
The method by which you place a disk under VxVM control depends on the circumstances:
vxdiskadm
utility to do this.
Caution Initialization destroys existing data on disks.
none
when asked to name a disk group. Do not confuse this type of "spare disk" with a hot-relocation spare disk.
Note Encapsulation preserves existing data on disks.
It is possible to configure the vxdiskadm
utility not to list certain disks or controllers as being available. For example, this may be useful in a SAN environment where disk enclosures are visible to a number of separate systems.
To exclude a device from the view of VxVM, select item 17 (Prevent multipathing/Suppress devices from VxVM's view
) from the vxdiskadm
main menu. See Disabling and enabling multipathing for specific devices for details.
