Linux Client RAID Connections and LUN Preparation

After the Linux InfiniBand drivers are installed or the Fibre channel HBA
drivers are installed and loaded (which is not covered in this manual), you
should already have the block device representing the LUN mounted. If you
type the following command you should get a list of mounted storage LUNs:

lsscsi[enter]

the following response will be displayed:

[0:0:0:0] disk ATA HDS722516VLAT80 V34O /dev/sda

[0:0:1:0] cd/dvd PIONEER DVD-RW DVR-109 1.40 /dev/sr0

[2:0:0:0] disk GalaxyIB MyLUN 2091 /dev/sdb

In the example above, the last line shows the Aurora LUN [GalaxyIB My LUN].
The Aurora device manufacturer is shown as GalaxyIB, with the My LUN name
as the model name. The version number, 2091, is the version of the Aurora
driver. Finally, you are most interested in the device name on the right
[/dev/sdb]. The next step for preparing to use this LUN is to label the device,
and create a partition on it. This is done with the Linux ‘parted’ command, by
typing the following:



CAUTION: This procedure erases all data on the LUN.



Important

: Be very careful typing these keyed entries in

bold type

.

Go to a new prompt and enter:

parted /dev/sdb[enter]

the responding command line interface is

displayed as

:

GNU Parted 1.8.7

Using /dev/sdb

Welcome to GNU Parted! Type 'help' to view a list of commands.

(parted)

mklabel[enter]

Warning: The existing disk label on /dev/sdb will be destroyed and all

data on
