MSA2012fc Connectivity with RHEL 5 Host - define mount points

MUHAMMAD RAHEEL LODHI_1 — Tue, 17 Aug 2010 04:09:19 GMT

Hi,

We have 1 "MSA2012fc DC MSA" connected with "DL580 G5 SERVER" directly through "HP FC1243 4GB PCI-X 2.0 DC HBA", i have to install RHEL 5.4 in DL580 G5 server, please guide me through steps to configure define mount points in the SAN.

P.S. MSA 2012fc have 10 x 146 GB 15k 3.5" SAS HDD and we have configured RAID - 1+0 with five equal partitions in it. snap shot attached.

In the 2012 you need to define the WWID of the HBA in the DL580 to access the LUNS created on the 2012. Once the HBA has the proper access, the OS should see the LUNS as /dev/sdX where X will be a letter i.e. /dev/sda, /dev/sdb etc etc

would you able to tell how can i configure the LUN's in Linux. what steps do i take to define the filesystem and place them in order of /u01, /u02 upto /u05 ?

once you can access the LUNS you need to create the directory structure then add the device and the mount point in /etc/fstab

# mkdir /u0{1,2,3,4,5}
# vi /etc/fstab

an example of /etc/fstab would be something like

/dev/sda /u01 ext3 defaults 1 2
/dev/sdb /u02 ext3 defaults 1 2
/dev/sdc /u03 ext3 defaults 1 2
/dev/sdd /u04 ext3 defaults 1 2
/dev/sde /u05 ext3 defaults 1 2

man fstab for more information
