SANtricity 11.8 Commands

Reset controller

The reset controller command resets a controller, and is disruptive to I/O operations.

Supported Series

This command applies to any individual storage system, including the HB2100/HB2200/HB2300, HB5100/HB5200, AB6100 and AB3100 series, as long as all SMcli packages are installed.

Roles

To execute this command on an HB2100/HB2200/HB2300, HB5100/HB5200, AB6100, or AB3100 storage system, you must have the Storage Admin role.

Context

When you reset a controller, the controller is removed from the data path and is not available for I/O operations until the reset operation is complete. If a host is using volumes that are owned by the controller being reset, the I/O directed to the controller is rejected. Before resetting the controller, either make sure that the volumes that are owned by the controller are not in use or make sure that a multi-path driver is installed on all of the hosts that use these volumes.

If you use in-band management, you cannot control which controller any command is sent to, and this command can have unexpected results.

Syntax

reset controller [(a|b)]

Parameters

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, the storage management software 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.
