Installation
6 Follow the screens to find information about the
array or to configure the array from the factory-
default settings. The Diamond-VT may be set
up in a RAID Level 5 or RAID Level 10
configuration with or without Hot Spare sleds
and/or set up in a zoned configuration.
If the Diamond-VT is not attached to a DHCP
server and you wish to change the defaults
1 At the Ready prompt after POST (see above),
type set IPAddress [desired IP address].
2 Type set IPSubnetMask [desired IP Subnet
Mask]
3 Type set IPGateway [desired IP Gateway]
4 Type SaveConfiguration Restart to save the
configuration and restart the Diamond-VT
5 After the powerup and POST complete, type
the IP address from step 1 above into your
browser.
6 The ATTO ExpressNAV screen appears. After
logging in (refer to Step 2b: connect to
Ethernet, Step 5 on page 5), follow the screens
to find information about the array or to
configure the array from the factory-default
settings. The Diamond-VT may be set up in a
RAID Level 5 or RAID Level 10 configuration
with or without Hot Spare sleds and/or set up in
a zoned configuration.
Step 3: set up Virtual Tape configuration
The simplest way to set up Virtual Tape
configurations is to use the ExpressNAV
interface. Refer to
ATTO ExpressNAV: Browser-based
Interface on page 23 for more information on the
interface. After logging in (refer to Step 2b:
connect to Ethernet, Step 5 on page 5 ), follow the
screens to find information about the array or to
configure the array from the factory-default
settings
.
If you use the CLI, the command QuickTape™
sets up Virtual Tapes using the following format:
set QuickTape [RAID5|RAID10] [# tape
volumes] [# tape drives] <enabled>
<Barcode Prefix>
Hot Spares are not available for all Virtual Tape
configurations. You must designate enabled to
allow Hot Spare sleds or disabled to forgo Hot
Spare sleds. Refer to and Optional Hot Spare Sled on
page 50 for more information and examples.
Each Hot Spare sled configuration requires a
certain number of Hot Spare sleds. These sleds,
once designated as Hot Spares, are not available
for other use.
• RAID Level 10: 10 drive sleds and two Hot Spare
sleds (sleds 11 and 12).
• RAID Level 5: 10 drive sleds and two Hot Spare
sleds (sleds 11 and 12)
• RAID Level 5: five drive sleds (sled positions 1
through 5) and one Hot Spare sled (sled 12).
You may specify the first four to six alpha-
numeric characters of a tape bar code, used by
tape backup software. The remaining four
characters will be entered by the system
automatically to identify the tape number. Refer
to
Virtual Tape on page 49 for more information and
examples.
Note
The maximum number of tape volumes and
tape drives for RAID Level 5 is 30.
The maximum number of tape volumes and
tape drives for RAID Level 10 is 15.
You must designate either enabled or disabled
for the Hot Spare option when designated a
barcode prefix.
All arrays using RAID level 10 and Hot Spare
sled options must be fully populated.
