Re: Linux Boot Options.

I still suggest you fix your boot dragginess issue with SAN LUNs enabled. I am seeing this issue in about 9 of 10 Colleaugues out there.

Symptoms of a misconfigured LVM.CONF that drags down boot up times of SAN connected systems are those "Duplicate PVs" detected on boot up or doing LVM gyrations.

Work also with your DBA to get your /etc/sysconfig/oracleasm config file to have ASMlib scan only what it should scan as well as "disk sting" within the Oracle ASM Instance.

I forgot to add, sometimes the issue would be with "Ghost LUNS" being seen by the Linux scsi stack. We've bee bitten by this on XP Arrays... There is a setting in the hostgroup definition to do away with Ghost or zero sized LUNs being presented,

What is that setting?

Re: Linux Boot Options.

That setting "varies" from SAN Array to another. On the HP Storageworks XP line - it is a HostGroup property -- ask your SAN admin if your array has that peculiarity.
