SANtricity 11.8 Commands ( CA08871-194 ~ 196 )

Test asynchronous mirror group connectivity

This command is not supported.

The diagnose asyncMirrorGroup command tests possible communication problems between the local storage system and the remote storage system associated with an asynchronous mirror group.

Supported Series

This command applies to any individual storage system, with some restrictions.

If you are running the command on the HB2100/HB2200/HB2300 or HB5100/HB5200 series, the client type must be set to symbol. This command will not execute if they client type is set to https.

Roles

To execute this command on an HB2100/HB2200/HB2300 or HB5100/HB5200 storage system, you must have the Storage Admin role.

Syntax

diagnose asyncMirrorGroup [asyncMirrorGroupName]
testID=(all | connectivity | latency | bandwidth | portConnections)

Parameter

Parameter Description

asyncMirrorGroup

The name of an existing asynchronous mirror group that you want to test. Enclose the asynchronous mirror group name in square brackets ([ ]). If the asynchronous mirror group name has special characters or numbers, you must enclose the asynchronous mirror group name in double quotation marks (" ") inside square brackets.

testID

The identifier for the diagnostic test you want to run. The identifier and corresponding tests are as follows:

  • All — Performs all the tests associated with this command.

  • Connectivity — Verifies that the two controllers have a communication path. The connectivity test sends an inter-controller message between the storage systems, and then validates that the corresponding asynchronous mirror group on the remote storage system exists. It also validates that the volume members of the asynchronous mirror group on the remote system match the volume members of the asynchronous mirror group on the local system.

  • Latency — Sends a SCSI test unit command to each volume on the remote storage system associated with the asynchronous mirror group to test the minimum, average, and maximum latency.

  • Bandwidth — Sends two inter-controller messages to the remote storage system to test the minimum, average, and maximum bandwidth as well as the negotiated link speed of the port on the controller performing the test.

  • Port connections — Shows the port that is being used for mirroring on the local storage system and the port that is receiving the mirrored data on the remote storage system.
