106.0. "HSZ40 / A2100 problem." by IB004::DELGADO (Jorge Delgado @ZQO) Mon May 12 1997 12:30




	Hi,

	We're having a problem with a dual HSZ40 configuration on a SW500
	cabinet connected to a A2100. Up to date, there were four raid5 sets
	(D1, D100, D200, D300) and a mirrorset, working fine. Last weekend
	we added two raid5 (D102 and D201). The problem is that the generation
	of a file that in any of the old raidsets took only 8 minutes, but on
	any of that new raidsets it takes 1,30 hours!  
	We suspect that there's a problem of subluns (D100 with D101 and D200 
	with D201), but can't tell who's responsible for that possible problem
	- if we are right- : the KZPSA, the HSZ40, the A2100 FW revision... ??


	The system is running UNIX 3.2B, the HSZ40 FW rev is 2.7, the A2100 
	SRM FW is 3.11 and pal osfcode is U.35.

	The customer has SAP version 2.2e, and cannot upgrade Unix because 
	of that. Another question would be: which is the higher SRM FW revision
	and pal osfcode can we install without putting on risk the integrity 
	of SAP ??
    

	Any help will be welcome.

	Jordi Delgado
