I added some new disks to a couple of HP servers including a 1RU stand-alone and a blade server recently, but in the end the fresh Xenserver has no Local Storage. Installing Xenserver 6.5 seemed to complete as expected, except that when I looked at the new server there was no Local Storage.<\/p>\n

A DVD drive and a USB Removable device were recognised correctly.<\/p>\n

I am still not clear on why it did not complete the process of preparing the Local Storage, but the following process resolved it for me.<\/p>\n

Postscript: I then went to the second blade server and found a different config partly completed during the install resulting in the same issue but a different method to address it. See my other post Xenserver install without Local Storage<\/a>.<\/p>\n

In a nutshell, Xenserver Dom(0) was installed but did not configure the rest of the disk as a usable device.<\/p>\n

Step 1. From the console identify the host uuid like this for the test server DS3001:<\/p>\n

# xe host-list
\nuuid ( RO)\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 : 4c2e3091-502f-47b8-8f64-64e8feba806b
\nname-label ( RW): DS3001
\nname-description ( RW): Default install of XenServer<\/p>\n

Step 2. Find the partition\/drive configuration:<\/p>\n

# cat \/proc\/partitions
\nmajor minor\u00a0 #blocks\u00a0 name<\/p>\n

7\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 0\u00a0\u00a0\u00a0\u00a0\u00a0 57216 loop0
\n104\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 0\u00a0 292935982 cciss\/c0d0
\n104\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 1\u00a0\u00a0\u00a0 4193297 cciss\/c0d0p1
\n104\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 2\u00a0\u00a0\u00a0 4193297 cciss\/c0d0p2
\n104\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 3\u00a0 284546333 cciss\/c0d0p3
\n104\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 16\u00a0 976729816 cciss\/c0d1\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 <<—\u00a0 this is the one we want as it is the largest partition
\n11\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 0\u00a0\u00a0\u00a0 1048575 sr0
\n11\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 1\u00a0\u00a0\u00a0\u00a0 589594 sr1
\n8\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 0 1953514583 sda
\n8\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 1 1953513559 sda1
\n8\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 16 1953514582 sdb
\n8\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 17 1953512534 sdb1<\/p>\n

and then get the UUID :<\/p>\n

# ls -lah \/dev\/disk\/by-id
\ntotal 0
\ndrwxr-xr-x 2 root root 180 Jul\u00a0 6 12:29 .
\ndrwxr-xr-x 7 root root 140 Jul\u00a0 6 12:29 ..
\nlrwxrwxrwx 1 root root\u00a0 16 Jul\u00a0 6 12:29 cciss-3600508b100103231372020202020000f -> ..\/..\/cciss\/c0d0
\nlrwxrwxrwx 1 root root\u00a0 16 Jul\u00a0 6 12:29 cciss-3600508b1001032313720202020200010 -> ..\/..\/cciss\/c0d1<\/p>\n

Step 3. Fill in the uuid and the device in to the following command:<\/p>\n

# xe sr-create content-type=user device-config:device=\/dev\/disk\/by-id\/<cciss-xxxxxxxxxxxxxxxxxxxxxxxxx> host-uuid=<host-uuid> name-label=\u201dLocal Storage 2\u201d shared=false type=lvm<\/p>\n

Using the examples, to create:
\n# xe sr-create content-type=user device-config:device=\/dev\/disk\/by-id\/cciss-3600508b1001032313720202020200010 host-uuid=4c2e3091-502f-47b8-8f64-64e8feba806b name-label=”Local Storage” shared=false type=lvm<\/p>\n

Run that command on Dom(0) console and the new Local Storage will appear in XenCenter.<\/p>\n
