Chapter 5 Configuring the xStack Storage Array
5.2.2.1
Physical Resources Tab
The
Physical Resources
tab contains the following physical resources:
The xStack Storage unit (
).
The physical drives attached to the xStack Storage Array (
).
The Ethernet ports on the xStack Storage Array (
). To enhance viewing, the port icons are
color coded (black = link is down, green = link is up).
5.2.2.2
Logical Resources Tab
The
Logical Resources
tab shows the following logical resources:
Unusable Collection
(
). Shows drives that have been pulled out of the xStack Storage
Array. Two types of drives appear in the
Unusable Collection
:
–
Drives not available for use because they have failed and have not been removed from
the enclosure.
–
Drives that were found to be used previously by an xStack Storage Array.
Initializing a drive in the
Unusable Collection
moves it to the
Available Pool
, where volumes
can be rebuilt if necessary.
Blade A Base Pool
(
). Shows drives (
) currently being used to hold volumes (
) or
ready to be used to hold volume data.
Available Pool
(
). Shows the available drives (
) that can be added to the storage pool.
Initially, all drives appear here until they are needed for use in a volume or dragged and
dropped by the administrator into the
Blade A Base Pool
. A spare drive is normally kept here
to keep it available for use should any other drive fail.
Target Resources
. Shows the network entities (
) and LAGs (
).
Initiator Resources
. Shows the iSCSI initiators (
) that have been created.
If a volume is reduced (for example, if a physical drive fails), the firmware
will automatically move a drive from the
Available Pool
to the
Blade A Base
Pool
if there is insufficient space to otherwise start a rebuild operation for
that volume.
