DSTAT

The DSTAT command displays the current status of the disk drives on the system.

Syntax

     DSTAT [ ldev

             ALL ]

Parameter

ldev: One number from 1 to 999 that specifies the logical device that is to be displayed. It must identify one unique device configured into the device class DISC. Optional.
ALL: Lists all of the disks connected to the system including the system volumes. Optional.

Example

This example shows the disk states that can be displayed in the DSTAT command when using mirrored disks.

The following table describes DSTAT disk states and whether data can be accessed on a volume in that state.

Table 5-4 DSTAT Disk States

State	Description	Accessible?
`MASTER`	A volume in this state is the master volume of a volume set. In order for the system to recognize the volume set, the master volume must be mounted.	Yes
`MEMBER`	A volume in this state belongs to a volume set whose master is mounted. If the master is not mounted, the volume is in the `LONER` state.	Yes
`MASTER-MD`	A volume in this state is the master volume of a mirrored volume set. In order for the system to recognize the volume set, the master volume must be mounted.	Yes
`MEMBER-MD`	A volume in this state belongs to a mirrored volume set whose master is mounted. If the master is not mounted, the volume would be in the `LONER` state.	Yes
`MASTER-SU`	A volume in this state is the master volume of a user volume set. In order for the system to recognize the volume set, the master volume must be mounted.	Yes
`MASTER-SB`	A volume in this state is the master volume of a backup volume set. In order for the system to recognize the volume set, the master volume must be mounted.	No
`MEMBER-SU`	A volume in this state belongs to a user volume set whose master is mounted.	Yes
`MEMBER-SB`	A volume in this state belongs to a backup volume set whose master is mounted.	No
`DISABLED-MD`	A volume in this state failed after it was mounted.	No
`LONER-SU`	A volume is in the `LONER-SU` state when the volume set is closed by the `VSCLOSE` command. This volume is marked as the user half of the pair.	No
`LONER-SB`	A volume is in the `LONER-SB` state when the volume set is closed by the `VSCLOSE` command. This volume is marked as the backup half of the pair.	No
`LONER`	A volume is in the `LONER` state when its master is not mounted, or when the volume set is closed by the `VSCLOSE` command.	No
`SCRATCH`	A volume in the `SCRATCH` state can be initialized. It may contain data, but by scratching the volume, the user has indicated that the data is no longer needed.	No
`UNKNOWN`	A volume in the `UNKNOWN` state does not have a label that the system can recognize. The volume may be from another system, it may be a new disk pack, or it may be a volume that has been formatted. An `UNKNOWN` volume is available for initialization.	No
