| [-instance ] }

If you specify the -instance parameter, the command displays detailed information about all fields.

[-device-id <text>] - Device ID

Selects the tape drive/media changer with the specified device ID.

[-node {<nodename>|local}] - Node

Displays detailed information about tape drives or media changers on the specified node.

[-device-type <text>] - Device Type

Selects the devices with the specified type of tape drive or media changer.

[-description <text>] - Description

Selects the tape drives/media changers with the specified description.

[-alias-name <text>] - Alias Name

Selects the tape drive/media changer with the specified alias name.

[-alias-mapping <text>] - Alias Mapping

Selects the tape drive/media changer with the specified alias mapping.

[-wwnn <text>] - World Wide Node Name

Selects the tape drives/media changers with the specified World Wide Node Name.

[-wwpn <text>] - World Wide Port Name

Selects the tape drive/media changer with the specified World Wide Port Name.

[-serial-number <text>] - Serial Number

Selects the tape drive/media changer with the specified serial number.

[-functional-status {unknown|normal|error}] - Functional Status

Selects the tape drives/media changers with the specified functional status of the device.

[-device-if-type {unknown|fibre-channel|SAS|pSCSI}] - Device Interface Type

Selects the tape drives/media changers with the specified interface type.

[-device-state {unknown|available|ready-write-enabled|ready-write-protected|offline|in-use|error|reserved-by-another-host|normal}] - Operational State of Device

Selects the tape drives/media changers with the specified operational state.

[-format <text>,…​] - Tape Cartridge Format

Selects the tape drives with the specified tape format.

[-error <text>] - Tape Error

Selects the tape drives/media changers with the specified error string.

[-initiator <text>] - Initiator Port

Selects the tape drives/media changers with the specified initiator port.

[-file-number <integer>] - File Number

Selects the tape drives/media changers with the specified file number. The file number is the number of file marks between the beginning of media and current logical position. File number gets modified on write file mark, and forward or backward space file operations. A value of -1 indicates unknown position on the tape media or tape not loaded in the tape drive.

[-block-number <integer>] - Block Number

Selects the tape drives/media changers with the specified block number. The block number is the number of logical blocks between the beginning of tape media or the prior file mark and the current logical position on the tape media. Block number gets modified on writes, reads, and forward or backward space over records (blocks). The block number also gets reset to zero when a file mark is crossed or another file mark is written that designates a new file. If the tape is back spaced to a prior file mark, the block number might be zeroed. A value of -1 indicates unknown position on the tape media or that a tape not loaded in the tape drive.

[-residual-count <integer>] - Residual Count of Last I/O Operation

Selects the tape drives with the specified residual count.
