LUN 114 could not be created : unrecognized error code (0x712d810a)

Probably best to open a case with EMC - what array and what flare release and what raid group were you using? Was there sufficient space in raid group? Were you using the GUI or CLI? If CLI, what version of CLI and what Operating System on host?

This is a CX4/960 with flare code 30 update 512.  We contacted support and they had us reboot each SP.

Everything works now.  So you gotta love all the bugs.

Please follow the primus as shown below.

The following is a Primus(R) eServer solution:

Symptom    NaviCimom 712d810a Failing Command: Create LUN

Symptom    

This configuration exceeds the array's Safe Operating Capacity, meaning that a storage processor (SP) could run out of CBFS memory and panic.

Change     Customer binding thin LUN on a thin pool.

Change     Customer expanding  a thin pool.

Note       0x712D810A --> MLU_EXECUTIVE_ERROR_OPERATION_WOULD_EXCEED_SAFE_OPERATING_CAPACITY - This error means that the attempted creation  of a pool LUN was not allowed because it would have left the array operating over its safe operating capacity.

Note       A clean-up operation will be required if expansion was started and then failed with "Could not complete operation Create LU due to 0xe12d810a" error. Escalate to TS2/Engineering.
