Dell PowerVault MD3420 - Manual (Page 250)

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 raidControllerModule [(0 | 1)]
Parameter
Parameter Description
raidControllerModule 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.
Reset Remote Replication Group Statistics
Description
This command resets the synchronization statistics for one or more member virtual disks in a remote
replication group to a relative 0.
