Checking Firmware Version Consistency

Independent 6 Gbit/s SAS interface modules: Run a CLI command to power an interface module off and on to rectify faults.

Operation Restrictions

  • 6 Gbit/s SAS interface modules can be powered off and then on to rectify faults only when disk enclosures and RAID groups are in normal states and no corresponding alarms are displayed. Check items include but are not limited to:

    Check the physical status of disks, the logical status of disks, the expansion module status, the enclosure status, and the RAID group status. Ensure no alarms of single link faults, disk faults, RAID group degradation faults, and RAID group faults exist.

  • Before rectifying faults, ensure that all port services on 6 Gbit/s SAS interface modules are stopped.
  • When faults of multiple 6 Gbit/s SAS interface modules need to be rectified, only one 6 Gbit/s SAS interface module can be powered off and then on at a time. After the first interface module passes the check, perform the same operations on the next one, and so forth.

Command

poweroffifmodule

Function

The poweroffifmodule command is used to power off the specified interface module on the specified controller.

Format

Description

Key Word and Parameter

Description

Default Value
-c controller id

Controller ID. The value can be a or b, and is case-insensitive.

None
-if interface module id

ID of the interface module. The value can be obtained by the showifmodule command.

None

Level

Super administrator

Usage Guidelines

  • This operation will cause that the services of all ports on the interface module are interrupted.
  • Before you perform this operation, ensure that the services of all ports on the interface module are stopped.

Example

The following uses S5500T as an example:

Power off interface module 0 on controller A.

admin:/>poweroffifmodule -c a -if 0
DANGER: You are going to power off the interface card.

This operation will disable all ports on the interface card.

Suggestion: Before you perform this operation, ensure that all services related to the interface have been stopped.
