Import a disk
You can import a ‘foreign’ disk into an ASC Server. A foreign disk is a
virtualized physical device containing ASC logical resources previously set up on
a different ASC server. You might need to do this if an ASC Server is damaged
and you want to import the server’s disks to another ASC Server.
When you right-click on a disk that ASC recognizes as ‘foreign’ and select the
Import
option, ASC scans the disk’s partition table. ASC then tries to
reconstruct the virtual drive out of all of the segments.
If the virtual drive was constructed from multiple disks, you can highlight
Physical Resources
, right-click and select
Prepare Disks
. This launches a wizard
that allows you to import multiple disks at the same time.
As each drive is imported, ASC marks the drive ‘offline’ because it has not yet
found all of the segments. Once all of the disks that were part of the virtual
drive have been imported, ASC re-constructs the virtual drive and marks it
‘online’.
Importing a disk preserves the data that was on the disk but does not preserve
the client assignments. Therefore, after importing, you must either reassign
clients to the resource or use the
Restore configuration option.
Note: The GUID (Global Unique Identifier) is the permanent identifier for each
virtual device. When you import a disk, the virtual ID, such as
SANDisk-00002
,
may be different from the original server. Therefore, you should use the GUID
to identify the disk.
SCSI device throughput
To check the throughput for a SCSI device:
Right-click on the device (under
Physical Resources
).
Select
Test
from the menu.
The system will test the device and then display the throughput results on the
screen.
