Displaying information for all disk devices associated with the nodes in a cluster


Displaying information for all disk devices associated with the nodes in a cluster
Prev	Configuring storage	Next

You can display disk information for the disk devices associated with the nodes in the Veritas Access cluster. If local disks are present, the information includes entries for the local disks.

See the storage_disk(1) man page for the detailed examples.

The information displayed depends on the form of the command that you use. The following information is available:

Disk	Indicates the disk name.
Serial Number	Indicates the serial number for the disk.
Enclosure	Indicates the type of storage enclosure.
Size	Indicates the size of the disk.
Use%	Indicates the percentage of the disk that is being used.
Transport	Indicates transport protocol values like SCSI, FC, and other values.
ID	ID column consists of the following four fields. A ":" separates these fields. VendorID - Specifies the name of the storage vendor, for example, HITACHI, IBM, EMC, and so on. ProductID - Specifies the ProductID based on vendor. Each vendor manufactures different products. For example, HITACHI has HDS5700, HDS5800, and HDS9200 products. These products have ProductIDs such as DF350, DF400, and DF500. TargetID - Specifies the TargetID. Each port of an array is a target. Two different arrays or two ports of the same array have different TargetIDs. TargetIDs start from 0. LunID - Specifies the ID of the LUN. This should not be confused with the LUN serial number. LUN serial numbers uniquely identify a LUN in a target. Whereas a LunID uniquely identifies a LUN in an initiator group (or host group). Two LUNS in the same initiator group cannot have the same LunID. For example, if a LUN is assigned to two clusters, then the LunID of that LUN can be different in different clusters, but the serial number is the same.
Array Type	Indicates the type of storage array and can contain any one of the three values: Disk for JBODs, Active-Active, and Active-Passive.

To display a list of disks and nodes

To display a list of disks and nodes, enter the following:
```
Storage> disk list
```
This form of the command displays local disk information for all nodes in the cluster.

To display the disk information

To display the disk information, enter the following:
```
disk list detail
```
This form of the command displays local disk information from all the nodes in the cluster.

To display the disk list paths

To display the disks multiple paths, enter the following:
```
Storage> disk list paths
```
This form of the command displays local disk information from all the nodes in the cluster.
