Parameter
Parameter
Description
controller
The controller that you want to reset. Valid controller identifiers
are a or b, where a is the controller in slot A, and b is the
controller in slot B. Enclose the controller identifier in square
brackets ([ ]). If you do not specify a controller owner, the
controller firmware returns a syntax error.
Notes
The controller that receives the reset controller command resets the controller specified. For example, if
the reset controller command is sent to controller A to request a reset of controller A, then controller A
reboots itself by doing a soft reboot. If the reset controller command is sent to controller A to request a
reset of controller B, then controller A holds controller B in reset and then releases controller B 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 and the expander chips in the controller.

Reset iSCSI IP address

This command resets the IP address for the remote storage subsystem to re-establish connection with the
local storage subsystem. You can use this command to notify the local storage subsystem that the iSCSI IP
address of the remote storage subsystem has changed and needs to be updated.
When you establish an Enhanced Global Mirroring relationship with an iSCSI connection, both storage
subsystems store the IP addresses of the remote storage subsystem. If the IP address of an iSCSI port
changes, the remote storage subsystem that is attempting to use that port encounters a communication
error.
The storage subsystem with the changed IP address sends a message to each remote storage subsystem
associated with the Enhanced Global Mirror Groups that are configured to mirror over an iSCSI
connection. Storage subsystems that receive this message automatically update their remote-target IP
address.
If the storage subsystem with the changed IP address is unable to send its inter-controller message to a
remote storage subsystem, the system sends you an alert of the connectivity issue. Use the reset
command to re-establish connection with the local storage subsystem.
