vserver nvme subsystem show
Display NVMe target subsystems
Availability: This command is available to cluster and Vserver administrators at the admin privilege level.
Description
The vserver nvme subsystem show
command displays information for NVMe subsystems.
Parameters
- {
[-fields <fieldname>,…]
-
If you specify the
-fields <fieldname>, …
parameter, the command output also includes the specified field or fields. You can use '-fields ?' to display the fields to specify. - |
[-instance ]
} -
If you specify the
-instance
parameter, the command displays detailed information about all fields. [-vserver <Vserver Name>]
- Vserver Name-
Use this parameter to display the NVMe subsystems that match the Vserver that you specify.
[-subsystem <text>]
- Subsystem-
Use this parameter to display the NVMe subsystem that matches the name that you specify.
[-ostype {aix|linux|vmware|windows}]
- OS Type-
Use this parameter to display the NVMe subsystems that match this parameter value.
[-comment <text>]
- Comment-
Use this parameter to display the NVMe subsystems that match this parameter value.
[-target-nqn <text>]
- Target NQN-
Use this parameter to display the NVMe subsystems that match this parameter value.
[-serial-number <text>]
- Serial Number-
Use this parameter to display the NVMe subsystems that match this parameter value.
[-default-io-queue-count <integer>]
- Default Number of Host I/O Queue Pairs-
Specifies the IO queue count inherited by hosts added to this subsystem. The actual value used when a connection is established may vary depending on the host and transport protocol used.
[-default-io-queue-depth <integer>]
- Default Host I/O Queue Depth-
Specifies the IO queue depth inherited by hosts added to this subsystem. The actual value used when a connection is established may vary depending on the host and transport protocol used.
[-uuid <UUID>]
- UUID-
Use this parameter to display the NVMe subsystems that have UUIDs matching the parameter value.
[-delete-on-unmap {true|false}]
- Delete on Unmap (privilege: advanced)-
Specifies whether the subsystem should be deleted automatically when it is no longer mapped to a namespace.
[-vendor-uuids <UUID>,…]
- Vendor UUIDs (privilege: advanced)-
Use this parameter to display the NVMe subsystems that have vendor-specific UUIDs that match the parameter value.
[-peer-vserver-name <text>]
- Peer Vserver Name-
Selects the subsystems that match this parameter value. The peer-vserver-name is the local name of the peer Vserver, as reported by the vserver peer show -fields peer-vserver command. When set, the subsystem and its hosts and maps to namespaces are replicated to the peer cluster.
[-replication-error <text>]
- Replication Error-
Selects the subsystems that match this parameter value. This field provides information about asynchronous errors encountered while replicating this subsystem. Subsystems within a peering relationship are replicated in the same stream, so the error reported here might be related to this subsystem or a prior replicated subsystem that is now blocking the replication of this subsystem. Both the error information and the subsystem encountering the error are reported. If the error is configuration related, it can be corrected on the referenced subsystem. The replication is retried using exponential backoff up to a maximum of one retry every 5 minutes. Every operation on the same stream triggers an immediate retry and restarts the exponential backoff starting with a 1 second delay. If the error is system related, the retries should correct the error when the system enters a healthy state.
[-replication-error-subsystem <text>]
- Replication Error Subsystem-
Selects the subsystems that match this parameter value. The name of the subsystem encountering the error reported by the 'replication-error' field.
