Is it a best practice recommendation to disable SP Write Cache on VNX RAID Group LUNs in a Oracle ASM configuration.
Leave the best practices, if you do that, it will never work.
Are you trying to disable it on a particular LUN, till the time you are configuring Oracle ASM or is it permanently ?
This was recommended by Oracle architect here claiming it as a EMC recommendation.
I was not affirmative though, never did or saw such a recommendation Just wanted to make sure.
I know that FAST cache is recommeneded to be disabled for Oracle archive and redo logs, do not see any use in disabling SP write cache
Thanks for the responses.
Your Subject line is a bit different. Now you may be correct. They may want to automate it by Oracle ASM.
Can you please tell me which Version (Oracle and VNX) and which white papers (if any) are they referring to ?
They did not refer to any white papers yet.
They got the SP write cache disabled but FAST cache enabled for all their database LUNs and FRA LUNs.
