Dell EqualLogic PS-M4110 Hardware Owner's Manual Chapter Identifying Control Module Failures
If two control modules are installed in the array, but only one is shown in the GUI (or CLI), make sure that you
have allowed enough time (two to five minutes) for the two control modules to boot and synchronize.
When synchronization completes, a message will appear on the serial console (if connected), and the ACT LED
on the secondary module will be orange.
If the GUI (or CLI) still shows only one control module after appropriate time has elapsed, the control module
may not be properly installed. In this case, reinstall the control module.
After reinstalling the control module, if both control modules still do not appear in the GUI (or CLI), contact
your support provider.
Warning: After a control module is installed in an array, do not restart or reinstall it, or upgrade firmware on the
array, until the control module has finished synchronizing its internal firmware with the primary control module.
If you interrupt the synchronization process, you will corrupt the control module's internal firmware, and the
control module will no longer function properly. In this case, contact your support provider
Replacing the microSD Card
Each control module includes a microSD card that contains the PS Series firmware.
If a control module fails, you need to remove the microSD card from the failed control module and install the
card in the replacement control module. This will make sure that the new control module is running the same
firmware as the other control module in the array.
Before you begin the procedure to replace a microSD card:
• Review Replacing a Control Module on page 39 for information about removing and replacing a control mod-
ule.
• Attach an electrostatic wrist strap, as described in Protecting Hardware on page 6 .
microSD Card Replacement Procedure
Use this procedure to replace the microSD card in your control module:
1. Remove the control module from the array. (As described in
Removing a Control Module on page 41
.)
2. Remove the SD card from the control module. (As described in Removing the microSD Card on page 47 .)
3. Install the replacement SD card in the control module. (As described in Inserting the microSD Card on page
48 .)
4. Insert the control module into the array. (As described in
Installing a Control Module on page 44
.)
