Solution Type Problem Resolution Sure Solution 1019405.1 : SAS WWID becoming unprogrammed
PreviouslyPublishedAs 239285 Symptoms When a probe-scsi-all is done after the domain has been up without doing a reset, the WWID can be deleted.

May 02 11:18:33 CDT 2008 May 02 11:18:33 CDT 2008 This must be fixed immediately using set-sas-wwid May 02 11:18:33 CDT 2008 MPT Firmware Fault, code 2000 Resolution To fix the issue power must be cycled twice. Specifically, use the "poweroff" and "poweron" commands for the domain twice. Power cycling the entire box is not necessary. Additional Information probe-scsi-all should not be run after the domain has been booted OBP uses a drop in mpt driver to access the LSI device. The state of the device is determined by the mpt driver in the OS. When these steps are followed the active WWN value gets trashed. If only part of the FLASH ROM is corrupted, the firmware might run, but it would use "default" parameters for any that are corrupted, and the "default" WWID is 0. This behavior is not a bug. probe-scsi-all should not be run after the domain has been booted. This operation is not supported.
