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 for determining the default disk group.
See "Rules for determining the default disk group" on page 177.
The method by which you place a disk under VxVM control depends on the following circumstances:
vxdiskadmutility to do this.
nonewhen asked to name a disk group. Do not confuse this type of "spare disk" with a hot-relocation spare disk.
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 multipathing and making devices invisible to VxVM" on page 145.
