Configuration of the IBM 245 disk array in Ubuntu server

1. Two HBA cards installed on the server with four wires connected to the disk array

2. Installing multipath-tools

3. Configure/etc/, Wwid can be obtained in multipath-v3

Defaults{user_friendly_names yes}blacklist{devnode "^SDA"}multipaths{multipath{wwid 36005076300810748b000000000000002alias mpath0path_grouping_policy Multibuspath_selector "Round-robin 0" failback Immediate}}

The default conf already has the configuration of the IBM 2145 disk array, so there is no need to write it in Conf.

Restart sudo service multipath-tools restart

4. For the sake of insurance, remove the previous multipath, sudo multipath-f, then run multipath-v3, rebuild the path, then run multipath-ll to view the path

5. Enter/dev/mapper/

Ls

6. Because the array is larger than 2T, partitioning with parted is not possible with Fdisk

Parted/dev/mpath0

Mklabel GPT

Mkpart 2048s 100%//can also be used with 0 100% if warning using 2048s

And finally found a mpath0p1 more.

7. Use MKFS.EXT3/DEV/MAPPER/MPATH0P1 to format this partition

8. Mkdir/mnt/raid, mount to sudo mount/dev/mapper/mpath0p1/mnt/raid

Using Df-h view, the last 11T disk is our array of disks

8. Set the automatic mount, get the UUID of the current partition, and then sudo vi/etc/ftabs, add a record
