BakStor Installation and Administration Manual 45
The RAID will now be available for creating disk and virtual tape slices. The disk and virtual
tape slices are created from the web interface for the BakStor Master Unit. The process is
identical to the normal process of creating slices. The RAID sets located on the BakStor
Expansion Unit will be available just like RAID sets located on the BakStor Master Unit.
Note: Once slices have been defined on the RAID sets located on the BakStor Expansion Unit
the unit can no longer be detached from the BakStor Master Unit. If detachment is required the
slices must be deleted. All data located on the slices will be lost.
5.1.5 Powering down a BakStor Expansion Unit
Once slices have been created on the BakStor Expansion Unit it is an integrated part of the
BakStor and cannot independently be powered down.
If it is required to power down the BakStor Expansion Unit (for example in order to physically
relocate it) both the BakStor Expansion Unit and the BakStor Master Unit must be powered
down.
In this case it is recommended to power down the BakStor Expansion Unit first, then power
down the BakStor Master Unit. It is strongly recommended to use the power-down option in the
menu system to shut the units down.
If it is required to permanently remove a BakStor Expansion Unit all slices located on the
BakStor Expansion Unit must be deleted. All data located on these slices will be lost.
Choose Storage Menu ? View slice location to observe what slices are located on the BakStor
Expansion Unit
Choose Storage menu ? Delete a storage slice to delete the slices that are located on the
BakStor Expansion Unit
Note: All data located on these slices will be lost
Choose BakStor EX ? Attach / Detach EX storage. Then click on “detach” for the RAID sets
located on the BakStor Expansion Unit.
At this point the BakStor Expansion Unit can be powered down and removed.
Caution!
Powering down or disconnecting a BakStor Expansion Unit that has attached RAID sets
will cause the BakStor Master Unit to be non-operational
5.1.6 Failover Ethernet for Expansion Unit
The BakStor Expansion Unit is provided with two Ethernet connections. By using a second
crossover cable the connection between the BakStor Master Unit and the BakStor Expansion
Unit can be configured for failover (AFT).
Configure the BakStor Expansion Unit first, then the BakStor Master Unit.
1. Using the web interface for the BakStor Expansion Unit, choose Configuration ?
