Dell 38XX, 34XX, 32XX, 36XX manual Reset RAID Controller Module, Reset controller 0

NOTE: The physicalDisk parameter supports both high-capacity expansion enclosures and low- capacity expansion enclosures. A high-capacity expansion enclosure has drawers that hold the physical disks. The drawers slide out of the expansion enclosure to provide access to the physical disks. A low-capacity expansion enclosure does not have drawers. For a high-capacity expansion enclosure, you must specify the identifier (ID) of the expansion enclosure, the ID of the drawer, and the ID of the slot in which a physical disk resides. For a low-capacity expansion enclosure, you need only specify the ID of the expansion enclosure and the ID of the slot in which a physical disk resides. For a low-capacity expansion enclosure, an alternative method for identifying a location for a physical disk is to specify the ID of the expansion enclosure, set the ID of the drawer to 0, and specify the ID of the slot in which a physical disk resides.

After power cycling the physical disk, the controller must verify the physical disk to be functional before it can be placed back into use. If the physical disk cannot be verified it is marked as a failed physical disk. Power cycling a failed physical disk requires global hot spare physical disks and full copy back to a replacement physical disk after it is brought into service.

Failed physical disks cannot be reset by a power cycle more than once in a 24 hour period, and in some cases cannot be reset more than once. Thresholds and counters for physical disk power cycles are kept in persistent storage, and are included in state capture data. Informational events are logged when a physical disk is power cycled.

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.
