Titan SiliconServer
Refresh
– This requests the software to
discover
any changes in the Fibre Channel connection,
i.e. find any newly attached devices and discover any devices that are no longer accessible. If
new devices are plugged into the Fibre Channel, use Refresh to identify them.
Assign Device to EVS
Select the
EVS
on which to assign the NDMP device. To allow the tape device sharing among all
EVS in a cluster, select
Any EVS
. A device assigned to a specific EVS cannot be shared unless it
is reassigned to
Any EVS.
Tape devices can be shared between EVS under the following conditions:
❑
The EVS must be within the same cluster.
❑
The tape device is not shared with another BlueArc SiliconServer.
❑
The tape device is not shared with another non-BlueArc device.
Note:
When an EVS is currently using a tape device, any attempt to use it
through a different EVS will prompt a notification that the device is
currently in use (i.e. the operation will not be queued).
When a tape device is currently assigned to a particular EVS (i.e. not ANY
EVS), any attempt to use it through a different EVS will prompt a
notification that the device has not been found.
Verifying NDMP Device Names
To configure a storage management application to work with NDMP, enter the names of the
autochangers and tape drives. The device names can be verified through the Backup SAN
Management page.
The Location field for each tape drive shows the name of the autochanger that holds the drive
and the position of the drive in the autochanger. For example, the location of the first drive in
autochanger
/dev/mc_d0l0
is
/dev/mc_d0l0 :1.
To update the display, click
Refresh
.
When the Web Manager cannot determine the location of a tape drive, it shows it as *unknown*.
This can happen when:
•
The tape library is offline.
•
The autochanger does not support the mechanism that the Titan SiliconServer uses to
query the tape drive location, or the autochanger has not been setup to accept this
query. Where this is the case, compare the serial numbers of the tape drives with
displays available in the tape library to verify the drive locations.
•
The autochanger and a tape drive within it are attached to different servers. In this case,
use the tape drive serial numbers to match the device name shown by one server with
the location shown on the other.
