Re: LUN become inaccessible

does it happened in any particular LUN(s)?

What is your cluster file system (Veritas or RAW) or oracle instance file systems(ASM)?

Re: LUN become inaccessible


why r u restaring Instance when LUN become ina accessible? You mean all the paths to LUN? DB restrat is not going to help with PATHrecovery. It may be a coincedence that both happend at the same time.

LUNs belongs to voting disks? or normal disk group?How is the DB reacting when it notice the LUN is not accesible. If voting disk is not available system may TOC.What is the oracle version ?
