Hello every one,
I'm trying to setup ASM in a two nodes RAC cluster 10.2 over SLES10. I want
to use multipath (with a EMC SAN CX500). Multipath is running ok, as I can see
all LUN's defined. But from runInstaller, I can?t see any of the devices /dev
/dm-xx than multipath has generated. I change definition of path to "/dev/dm-*"
and "/dev/disk/by-name/*" with no results. It's supossed that raw devices are
not necessary.
So, I defined in /etc/raw 12 equivalences to dm-xx devices, but after restart
servers only 9 raw names appears in /dev/raw, and from runInstaller, only 6 of
them appears as candidates with path "/dev/raw/*". For SLES, all dm-xx devices
are availables.
No one of this devices has partitions defined.
Any suggestion?
This time are real servers, not vmware, for migrate a 9.2 RAC database to these
new servers.
Any suggestion?
