Hello all,

Hi Marek,
Just to clarify.

This problem only affects newer IA systems which have an internal RAID array, at present that can be rx3600, rx6600 and rx2660. It can therefore only affect 11.23 systems.

PHSS_35807 will have the fix for this, it is due to be released very soon.

Hi Marek,
I'm afraid I can't be more definite, I'm expecting it to be available by the end of next week.
