XenServer: Create RAID SR.

A quick How-To: on adding a RAID array as an SR in XenServer, the version I personally used was 5.6 but 5.5 and 5.0 should be identical.

Steps to create an SR in a Xenserver.

Locate the RAID array partition.

cat /proc/partitions

This returns a list of all partitions, find the RAID array and make note of it's name (sda, sdb, sdx, etc.).

Now locate the disk-id.

ll /dev/disk/by-id

This lists disk ID's, look for the ID that matches the partition name from the previous step.

Obtain the XenServer host-uuid, we need this because we need to specify the XenServer as the host to attach the SR to in the next step.

xe host-list

Create the SR.

xe sr-create content-type=user device-config:device=/dev/<sdx> host-uuid=<host-uuid> name-label=”RAID Array” shared=false type=lvm

You should now be able to see (and use) your RAID array in XenCenter.

App-V Error: 4A-40000194

There are a few possible problems here but I find the most common is that the OSD is not pointing to either the right location, deployment method, or both.

Check the OSD's (or go in via the Sequencer if you wish, but that will typically generate a new version of the .sft, though I haven't tried in 4.6SP1, maybe that was one of the two things they got right) to ensure the correct method and location are specified.

Remember that typically speaking it will be something like:
":<port>/<appsubfolder>/<pathtosft>"

And seldom if ever:
":<port>/<pathtosft>"
