Symptoms
Netra[TM] T1400 and Netra[TM] T1405 platforms may report hardware failures after installation of patch:

Patch ID: 110208-18 or Patch ID: 110208-19.
These events include reported fan failures, reported PSU failures and alarms being turned on and off. The fault LED may also be illuminate.

These failures were not seen for Patch ID: 110208-17 and lower.

All failures are false positives which means they are not real failures but these errors must not be ignored.
This is because Solaris[TM] and LOM monitor each other with what's called a watchdog timer. If Solaris or LOM disconnect from each other due to this issue for long enough, a watchdog reset may occur and the platform will reboot.

Resolution
The resolution for this issue was released in LOM:

Patch ID: 110208-20 but always update to the latest patch where possible, currently Patch ID:110208-22.

The resolution is as follows:

Download Patch ID: 110208-22 from Sunsolve[SM]

At a Solaris[TM] root prompt, issue the following:

# /usr/sbin/patchadd 110208-22

Then perform a reconfigure reboot:

# /usr/sbin/reboot -- -r

When the platform returns to multi user mode, this issue will be resolved.

Relief/Workaround

This may prevent platform resets until the patch can be added.
