Creating A Custom Setup - ATTO Technology FastStream SC 5300 Installation And Operation Manual

Creating a custom setup

If the application setups do not suit your needs, you
may use Custom Setup to configure the FastStream.
After choosing Custom Setup button, the
1
RAID Setup Wizard page appears. Click on
Next .
2 Decide if all drives are to be available to both
ports.
• If you select Yes , the same node name is
assigned to both ports.
• If you select No , different node names are
assigned to each FC port.
• The choice you make establishes the access
for all RAID groups attached to this
FastStream.
3 Select a RAID level. Refer to
Groups on page xix of the Appendix.
If you selected RAID 1 with Multiple Mirrors ,
type in the number of mirrors (copies) of the
original data you want to maintain in the box
provided.
4 Type a unique name for your RAID group in the
box provided on the page under the Step 3
heading.
5 Click Next.
6 For the FastStream 5700: If an SES enclosure
is found and it has drives associated with it,
choose a method for selecting drives from the
following:
a. Use all drives in an enclosure for your RAID
Group
b. Use all drives in an enclosure for your RAID
Group plus one for a Dedicated Hot Spare
(parity tye RAID)
c. Select your own drives
7 Click on the System Scan button to discover
the drives available for RAID configuration.
8 When the scanned drives box is populated,
click on the boxes representing the drives for
the RAID group named in
Design RAID
Step 4.
9 Click Next .
10 The Partition wizard appears.
• A RAID group may have several Terabytes of
total data capacity because of the size of the
included drives. Partitions allow you to break
up large RAID groups into smaller, more
manageable groups.
• Most host systems can address only 2 TB per
LUN. Partitioning increases storage
efficiency by providing more LUNs without
using lower capacity RAID groups.
• Partitioning allows the creation of multiple
logical volumes.
Note
If you don't want to use partitions, click on the
All Unallocated button.
a. Enter the desired partition size from the
available RAID group capability.
b. Click Create .
c. Repeat entering the partition size and
clicking on Create as often as you need to
partition the remaining capacity. Whenever
you have completed designating partitions,
click on the All Unallocated button to put
all the remaining capacity into one partition.
11 Click Next . The storage capacity is allocated.
12 RAID partitions are mapped onto the Fibre
Channel network as FC LUNs. Select the
method you wish to use to map the partitions.
• If you select Auto , all mapping for all RAID
groups attached to this FastStream is
changed, destroying any previous mapping.
• If you do not wish to change the mapping of
your other RAID groups, select Manual .
Manual mapping allows you to make LUN
assignments for each RAID partition in the
selected RAID group.
a. From the RAID Configuration page
presented, under Select the mapping
method, click the Manual radio button.
b. Click on any partition to map that partition to
a Port and LUN.
13 Choose an Initialization method (refer to
Initialization on page 12).
14 Select an Interleave level by clicking on the
drop down box.
