Reset RAID Controller Module

Description

This command resets a RAID controller module.

NOTE: When you reset a RAID controller module, the RAID controller module is not available for I/O operations until the reset is complete. If a host is using virtual disks owned by the RAID controller module being reset, the I/O directed to the RAID controller module is rejected. Before resetting the RAID controller module, either verify that the virtual disks owned by the RAID controller module are not in use or ensure a multipath driver is installed on all hosts using these virtual disks.

Syntax

reset controller [(0 | 1)]

Parameter

Parameter

Description

controller

RAID controller module to reset. Valid RAID controller module identifier values are 0 and 1. The identifier value is 0 for the RAID controller module on the top and 1 for the RAID controller module on the bottom when viewed from the rear of the enclosure. You must put brackets ([ ]) around the RAID controller module identifier. If you do not specify an owner, the RAID controller module firmware returns a syntax error.

Additional Information

The RAID controller module that receives the reset RAID controller module command resets the RAID controller module specified. For example, if the reset RAID controller module command is sent to RAID controller module 0 to request a reset of RAID controller module 0, then RAID controller module 0 reboots itself by doing a soft reboot. If the reset RAID controller module command is sent to RAID controller module 0 to request a reset of RAID controller module 1, then RAID controller module 0 holds RAID controller module 1 in reset and then releases RAID controller module 1 from reset, which is a hard reboot. A soft reboot in some products only resets the IOC chip. A hard reboot resets both the IOC chip and the expander chips in the RAID controller module.
