Displaying Disk Information
Before you use a disk, you need to know if it has been initialized and
placed under Volume Manager control. You also need to know if the disk
is part of a disk group, because you cannot create volumes on a disk that
is not part of a disk group. The vxdisk list command displays device
names for all recognized disks, the disk names, the disk group names
associated with each disk, and the status of each disk.
To display information on all disks that are defined to the Volume
Manager, use the following command:
# vxdisk list
To display details on a particular disk defined to the Volume Manager,
use the following command:
# vxdisk list (
disk_name
)
Displaying Multipaths Under a VM Disk
The vxdisk command is used to display the multipathing information for
a particular metadevice. The metadevice is a device representation of a
particular physical disk having multiple physical paths from the I/O
controller of the system. In the Volume Manager, all the physical disks in
the system are represented as metadevices with one or more physical
paths.
To view multipathing information for a particular metadevice, use the
following command :
# vxdisk list (
device_name
)
For example, to view multipathing information for c1t0d3, use the
following command:
# vxdisk list c1t0d3
The output is as follows:
Device: c1t0d3
devicetag: c1t0d3
type: simple
hostid: zort
