Hi

I am looking it from a prespective off SLA's for ex the document mentions

a)Establishing dependencies between clusterware storage and RAC databases to ensure that the shutdown in the correct sequence.The sun clusterware allows the oracle clusterware to be stopped before the filesystems are stopped.

b)It also suggests that there is a scope for oracle clusterware to evict a node and yet not reboot it immedaitely .The remaning nodes start recovering the transactions however the evicted continues to write to the datafiles during the period of eviction to the point where it falls down to the boot prompt it will lead to corruption

There are some other points
Like
a)interconnect connect being single point of failure b)How to provision voting disks and OCR should i ask the storage admins to carve out 5 1GB LUNS so i can mirror them ?
c)Would the storage admin object if i ask 5 1GB luns to be carved out for me as mostly they allocate LUNS of 64 GB 100Gb etc

regards
Hrishy
