Dot Hill Systems II 200 FC - Manual (Page 116)

7-8 SANnet II 200 FC, SATA, and SATA SE Array Installation, Operation, and Service Manual • March 2005
A controller that replaces a failed unit in a dual-controller system often has a newer
release of the firmware installed than the firmware in the controller it replaced. To
maintain compatibility, the surviving primary controller automatically updates the
firmware running on the replacement secondary controller to the firmware version
of the primary controller.
Note –
When you upgrade your controller firmware in the Solaris operating system,
the format(1M) command still shows the earlier revision level. To correct this, you
must update the drive label using the autoconfigure option (option 0) of the
format
(1M) command. When you select label, the drive is labelled with the
updated firmware version.
7.4.3 Upgrading SES and PLD Firmware
When you replace an I/O controller, the new controller might have a version of SES or
PLD firmware different from the other controller in your array. If this mismatch
occurs, when you install a controller you hear an audible alarm and see a blinking
amber Event LED.
To synchronize the SES firmware and hardware PLD versions, you must download
new SES firmware through SANscape software or the SANscape Command-Line
Interface (CLI).
If you have not installed this software, you must install it from the software CD that
shipped with your array.
■
Refer to the SANscape User’s Guide to see instructions for downloading firmware
for devices.
■
Refer to the SANscape CLI User’s Guide, or the sccli(1M) man page for similar
instructions using the SANscape CLI.
■
Refer to the SANnet II 200 FC, SATA, and SATA SE Array Release Notes for
instructions about where to obtain the firmware that you need to download.
When you open the SANscape software or the SANscape CLI and connect to the array,
an error message alerts you to the mismatched version problem.
7.5 Replacing the Front Bezel and Ear Caps
Some procedures require that you remove the front bezel and the small vertical plastic
caps on either side of the bezel that cover the rackmount tabs. These rackmount tabs
are referred to as “ears.”
