Should I partition the disks using fdisk (300 GB lun) for ASM?

695862Jul 14 2009 — edited Jul 15 2009

We've configured oracle 11g and asm on SLES10sp2 systems prior to the one I'm working on now. We use disks that are luns from SAN storage. The SAN devices vary (Tier 1 and tier 2). In earlier installs, we did not need to partition the disks using fdisk (luns up to 40GB in size). We did need to write a label using fdisk and 'w'. The asm that is being configured now is using 300 GB luns (on sles10 sp2 oracle 11g). I've needed to create a new primary partition using fdisk and then have asm 'look' as the partitioned device. If I did not do that, ASM would not look at the unpartitioned device.
The database in now built and it seems to be working ok.
Does this config sound ok?
Thanks,
Eleanor
