Using The Cli; Removing A Controller Module Or Expansion Module - Seagate Dot Hill AssuredSAN 3000 Series Installation And Replacement Manual

NOTE: See AssuredSAN 3000 Series RAIDar User Guide for additional information.

Using the CLI

1. Log-in to the CLI using default user manage and password !manage.
If the default user or password — or both — have been changed for security reasons, enter the secure
login credentials instead of the system defaults shown above.
2. In a dual-controller system, verify that the partner controller is online by running the command:
show redundancy-mode
3. Shut down the failed controller — A or B — by running the command:
shutdown
The blue OK to Remove LED (back of enclosure) illuminates to indicate that the controller module can
be safely removed.
4. Illuminate the identification LED of the enclosure that contains the controller module to remove by
running the command:
set led enclosure 0 on
NOTE: See AssuredSAN 3000 Series CLI Reference Guide for additional information.

Removing a controller module or expansion module

IMPORTANT:
• In a single-controller configuration, if you desire to transport CompactFlash to a replacement
controller, remove the controller module only after the cache is copied to CompactFlash, which is
indicated by the Cache Status LED being off. Transporting of cache must be performed by a
qualified service technician.
• In a single-controller environment, you must stop I/O and power off the enclosure before replacing
the controller module.
• In a dual-controller environment, you may hot-replace a controller module in an operational
enclosure, provided you first shut down the faulty controller using either RAIDar or the CLI.

NOTE: Within these procedures, illustrations featuring controller module face plates are generic. They do
not show host ports, and they pertain to all 3000 Series controller module models. For illustrations of
model-specific controller face plates, see the AssuredSAN 3000 Series Setup Guide.
1. Verify that you have successfully shut down the controller module using RAIDar or the CLI.
2. Locate the enclosure whose Unit Locator LED (front right ear) is illuminated, and within the enclosure,
locate the controller module whose OK to Remove LED is blue (rear panel).
3. Disconnect any cables connected to the controller.
Label each cable to facilitate re-connection.
4. Turn the thumbscrews counterclockwise until they disengage from the controller (see
page 33).
