Attach the SR Snapshot to the Secondary
XenServer Host
Make the snapshot volume available to the secondary XenServer host by
attaching the SR. For snapshots of iSCSI volumes, just attach the SR to the
XenServer host using XenCenter.
If the snapshot resides on a Dell PowerVault™ MD3000 RAID enclosure,
follow the steps below to attach the snapshot as an SR to a XenServer host.
1
Note the universally unique identifier (UUID) of the SR for which the
snapshot was created. You can identify the SR by its name label by running
the following command on the primary XenServer host:
# xe sr-list
2
Run the following command:
# xe sr-introduce content-type=user name-label=
SAS_snapshot type=lvmohba uuid=<sr_uuid>
3
To identify the disk ID of the storage volume, run the following command:
# ls -ltr /dev/disk/by-id
4
To identify the host UUID, run the following command:
# xe host-list
5
Run the following command:
# xe pbd-create device-config:device=/dev/disk/by-
id/<disk_id> host-uuid=<host_uuid> sr-uuid=
<sr_uuid>
6
To identify the PBD UUID, run the following command:
# xe pbd-list
7
Run the following command:
# xe pbd-plug uuid=<pbd_uuid>
