ATTO Technology VT-Class manual Set up Virtual Tape configuration, Configuration examples

6Follow 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

1At the Ready prompt after POST (see above), type set IPAddress [desired IP address].

2Type set IPSubnetMask [desired IP Subnet

Mask]

3Type set IPGateway [desired IP Gateway]

4Type SaveConfiguration Restart to save the configuration and restart the Diamond-VT

5After the powerup and POST complete, type the IP address from step 1 above into your browser.

6The 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 [RAID5RAID10] [# 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.

Configuration examples
