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 an 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. This can be done by typing the following command
on the primary XenServer host and identifying the SR by its name label in
the command output.
# xe sr-list
2
Type the following command:
# xe sr-introduce content-type=user name-label=
SAS_snapshot type=lvmohba uuid=<sr_uuid>
3
Identify the disk ID of the storage volume. Type the following command:
# ls -ltr /dev/disk/by-id
4
Identify the host UUID. Type the following command:
# xe host-list
5
Type the following command:
# xe pbd-create device-config:device=/dev/disk/by-
id/<disk_id> host-uuid=<host_uuid> sr-uuid=
<sr_uuid>
6
Identify the PBD UUID. Type the following command:
# xe pbd-list
7
Type the following command:
# xe pbd-plug uuid=<pbd_uuid>
