Configuring Storage 27
3 If you are configuring storage on the PowerVault MD3000 and MD32 x 0
RAID enclosures for a XenServer pool, add all hosts to the XenServer pool.
Ensure that the newly-created virtual disk is visible to all mapped hosts.
Log in to the XenServer local console shell on each XenServer host and
run the following command:
# mppBusRescan
4
On the XenServer host or pool master, identify the disk ID of the
PowerVault MD3000 and
MD32x0 storage volumes.
To get the SCSI device name for the storage volume run the following
command:
# /opt/mpp/lsvdev
The output of this command is similar to the following:
[root@xs1~]# /opt/mpp/lsvdev
Array Name Lun sd device
-------------------------------------
MD3000_Array1 0 -> /dev/sdc
Note the SCSI device name (/dev/sdX) and find the corresponding disk ID
in the output of the following command:
#
ls -ltr /dev/disk/by-id
The output of this command is similar to one below:
scsi-36001c23000c967da00000bae47ecaeeb ->
../../sdc

To create an SR on the PowerVault MD3000 and MD32 x 0 virtual disks, run
one of the following commands:
• If you are adding storage to a pool, run the following command:
# xe sr-create content-type=user name-label=
<label_of_SR> shared=true type=lvmohba device-
config:device=/dev/disk/by-id/<disk_id>
