HP 6G Virtual SAS Manager User Guide

Resetting the VSM software, the switch or attached storage enclosures
IMPORTANT: This task disrupts host I/O to the storage enclosures. Open a maintenance window
before resetting devices.
To restart the VSM software, or the switch or an attached zoned SAS storage enclosure such as
the MDS600, D2600, or D2700, use the following command description:
Syntax <TARGET> reset [hardware|software] [type=parallel] [forced]
Example 1: This example demonstrates restarting the switch:
=> switch loc=local reset hardware
Example 2: This example demonstrates resetting both switches at the same time (dual-domain
environments):
=> switch all reset hardware type=parallel
IMPORTANT: Reset both switches at the same time only when a system maintenance window is
open and all system traffic is halted.
Example 3: This example demonstrates restarting the VSM application on the switch (required after
updating switch network settings):
=> switch loc=local reset software
Example 4: This example demonstrates restarting storage enclosures connected to ports 3 and 4
of the switch in BladeSystem interconnect bay 5:
=> storageenclosure portbox=53:1,54:1 reset hardware
Example 5: This example demonstrates restarting all storage enclosures connected to the switch:
=> storageenclosure all reset hardware
NOTE: If the reset command does not execute successfully or displays an error message,
consider the following:
• Storage enclosure model—Only supported storage enclosures can be reset.
• Switch status—If the status is a value other than Active or Not Redundant, resetting the storage
enclosure is not allowed.
• Server blade status—All server blades in the c-Class enclosure with access to the storage
enclosure being reset must be powered off to perform this task.
• VSM activity—If the VSM GUI or VSM CLI is already processing a firmware update on a
switch or storage enclosure, this command request cannot be processed.
Issue the rescan command to ensure displayed information is up-to-date. Correct any issues before
proceeding.
