I have two little rx2660's running Oracle RAC on HPUX 11.31 connecting to an EVA4100.
I have created an additional LUN on the EVA and presented the disk to both rx2660's. However when I presented it to the second 2660 it turned out that the persistent DSF allocated by the first 2660 was already in use on the second and has therefor allocated a different one.
I am open to suggestions on how to get the same persistent DSF on both servers.
Regards

Re: Persistent DSF for Oracle RAC
According to what docs I have managed to read it seems this is the only way of doing it, and there is a much reduced risk of permissions problems after an insf command.
Thanks for your assistance.

Re: Persistent DSF for Oracle RAC
The use of mksf is all good and well but since my disks are multipath devices I would prefer to use the persistent DSF's to retain the redundancy.
Would
mkdir /dev/oracle
ln -s /dev/rdisk/disk142 /dev/oracle/oradb
work?
