/dev/sdd is the device path that is required for the next commands and is dependent upon
configuration. For example, it may be /dev/sdg or /dev/sdaa. Note the relation of the device by-
path to the iSCSI IQN target name for the volume.
Step 4 – From the XenServer console in XenCenter. The XPSP2-02-RS-1 storage repository, mapped
to device path /dev/sdd, is now used to locate and verify the SR UUID. Note that the appropriate
device path value must be used from what was found in Step 3. On the console command line, type:
pvscan | grep –I “/dev/sdd”
The portion that is of interest is after VG_XenStorage. Highlight this value and copy it to a notepad
document or write down the long UUID string. In this example: VG_XenStorage-13a7f4d6-75c7-
8318-6679-eb6702b11de1.
Step 5 – From the XenServer console in XenCenter. The XPSP2-02-RS-1 storage repository physical
volume attributes, mapped to device path /dev/sdd, is now changed. Note that the appropriate
device path value must be used from what was found in Step 3. On the console command line, type:
pvchange --uuid /dev/sdd
The command should return that the physical volume “/dev/sdd” changed.
Step 6 – From the XenServer console in XenCenter. The XPSP2-02-RS-1 storage repository volume
group attributes, mapped to the volume group VG_XenStorage-13a7f4d6-75c7-8318-6679-
eb6702b11de1, is now changed. Note that the appropriate volume group path value must be used
from what was found in Step 4. On the console command line, type:
vgchange --uuid VG_XenStorage-13a7f4d6-75c7-8318-6679-eb6702b11de1
The command should return that the volume group “VG_XenStorage-13a7f4d6-75c7-8318-6679-
eb6702b11de1” successfully changed.
