Configuring Storage 43
Creating an SR on a PowerVault MD3000 RAID Enclosure
Follow the steps below to create an SR on a storage volume on a PowerVault
MD3000 RAID enclosure.
1 Create and configure a virtual disk using the MD3000 Modular Disk
Storage Manager software (installed on your management station). Ensure
that the newly-created virtual disk is controlled by the RAID controller to
which your XenServer hosts have access.
2 Map the newly-created virtual disk to the XenServer hosts. For more
information on managing hosts and virtual disks on the MD3000, refer to
the MD3000
Users Guide available on the Dell Support website at
support.dell.com .
3 If configuring storage on MD3000 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
type the following command:
# mppBusRescan
4
On the XenServer host or pool master, identify the disk ID of the
PowerVault MD3000 storage volume:
Type the following command to get the SCSI device name for the storage
volume:
# /opt/mpp/lsvdev
The output of this command is similar to one below:
[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
