Dear erman,

In one of the site written by you..

The disks which will be presented by SAN should be in form of 8 lun( For ex:  rather than having 1x 1600 gb , we prefer  8x200 gb luns) We want 8 luns because the environment has multipath with 2 active paths, thus we prefer active path *4 luns for ASM. Disks should be aligned for ASM use..

We need 600gb for data diskgroups and 600 go for RECO disk group.We are going for 3 Luns each of 200 Gb for data dg and 3 Luns for reco dg.We have 2 paths.

 1)selecting number of Luns have any dependency on io path as well?
2)will there be any option in storage to make same lun available to both rac servers?Any idea how they will achieve this briefly.

Pls suggest best practice.

Thanks,
Satish
