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 161.
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.
pvremove, before attempting to initialize the disk for VxVM.
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 129.
