Controller Enters Maintenance Mode
When a RAID controller encounters and internal problem, it can enter
maintenance mode
. Maintenance mode is only for remedial action in the event of
a problem with the controller.
When an controller enters maintenance mode, it goes offline and it will display
Missing
under Readiness Status.
Note that VTrak subsystems with only one controller will always show that the
second controller is “Missing.” For VTraks with two controllers, one of the
controllers will enter maintenance mode for any of the following reasons:
•
The “missing” controller is improperly connected
•
The “missing” controller was removed from the subsystem
•
One controller has different hardware compared to the other
•
One controller is Fibre Channel and the other is SAS
•
Each controller has a different size of memory
•
Each controller sees a different set of configured drives
•
Each controller is running a different version of firmware
To obtain this information for a controller, click on the Controller
icon,
Information tab, and look for Firmware Version and Memory Size.
To access the controller, use a serial connection. If you know the controller’s IP
address, you can access the controller using a Telnet connection.
To log into the VTrak CLI:
1.
Change your terminal emulation program settings to match the following
specifications:
•
Bits per second: 115200
•
Data bits: 8
•
Parity: None
•
Stop bits: 1
•
Flow control: none
2.
Start your PC’s terminal VT100 or ANSI emulation program.
3.
Press Enter once to launch the CLI.
4.
At the Login prompt, type
administrator
and press Enter.
5.
At the Password prompt, type
password
and press Enter.
6.
At the administrator@cli> prompt, type
ctrl
and press Enter.
The controller status will display. The controller whose Readiness Status is
Missing
is in maintenance mode.
