Mount SAN Volume Oracle Linux
iSCSI is used as an alternative to FibreChannel San, and is relatively easy to setup and configure. This allows failover, and other wonderful features that SAN provides, therefore it makes sense to use it for Oracle Linux and Oracle Database. Let’s get Started!

at this point we are assuming that you have a BOND to a SAN network, and that the adapters are configured, we just need to do the Linux software portion. If not, configure a bond here
login and su to root
install the iSCSI initiator tools (these are required to mount the volume)
perfect, installed at this point
at this point we should set the iSCSI service to start after a reboot (otherwise you may have some issues)
from here we need to configure iscsi (only if you are using a username/password)
normally you would un-comment the following lines and modify if you were to configure a username/password
we did not in this example, so we will move on
the next step is to discover our targets
this connected to the SAN and sent the targets, so we should have a few block devices available
if we do a fdisk -l that will show us our available disks
THIS IS WHERE YOU NEED TO BE CAREFUL!!!
in this scenario, we have one local disk /dev/sda, and anything extra that shows up is a SAN volume, It’s up to you at this point to know what disk is the right one
we have /dev/sdb and /dev/sdc available
/var/log/messages | tail should show the newer added disks if you are unsure ex:
That’s it! You have mounted your iSCSI disk to Oracle Linux, from here’ it’s up to you how you want to format/configure the block device.
There is a suggestion here, but is provided as a suggestion, please be smart and make a backup, especially when formatting drives. NOT RESPONSIBLE FOR DATA LOSS!
