Delete raw links to Multipath Devices on all nodes:
rm -f /dev/raw/*
Shut down multipath:
multipath -F #shuts off Multipath
Looking at the multipath.log output file, you can see which block devices will used for Oracle CRS.
To be sure you have the correct disk on all nodes, look at /proc/partitons. In this installation
example, each device has a unique size so it is easier to map. Now link the block devices to the raw
devices on all nodes by modifying /etc/sysconfig/rawdevices. Run ll on the device to get the
major minor number for a block device, as seen below.
# ll /dev/sdc1
brw-rw---- 1 root disk 8, 33 Oct 1 12:46 /dev/sdc1 #ocr1
# ll /dev/sdd1
brw-rw---- 1 root disk 8, 49 Oct 1 12:47 /dev/sdd1 #ocr2
# ll /dev/sde1
brw-rw---- 1 root disk 8, 65 Oct 1 12:47 /dev/sde1 #vote1
# ll /dev/sdg1
brw-rw---- 1 root disk 8, 97 Oct 1 12:48 /dev/sdg1 #vote2
# ll /dev/sdh1
brw-rw---- 1 root disk 8, 113 Oct 1 12:49 /dev/sdh1 #vote3
Change the configuration file /etc/sysconfig/rawdevices using vi or your favorite editor and add
the following block devices.
$ vi /etc/sysconfig/rawdevices
