Working With Single-level Containers

In the following example, the

container create raid5

command with the /wait switch creates a RAID-5 set and returns the
prompt after the RAID-5 set is created.

HPN0> container create raid5 /wait=TRUE ((2,1,0), 100M)

(2,2,0)(2,3,0)

Executing: container create raid5 /wait=TRUE

((CHANNEL=2,ID=1,LUN=0), 104,857,600) (CHANNEL=2,ID=2,LUN=0)

(CHANNEL=2,ID=3,LUN=0)

Understanding How to Create a RAID-5 Set

This section provides an example that describes how to create a
RAID-5 set.

Before creating a RAID-5 set, use the

disk show space

command

to display information about your disks, as in the following
example. In the example, the Usage column indicates Free for each
disk, which means that the space on each disk consists of freespace.

HPN0> disk show space

Executing: disk show space

Scsi C:ID:L Usage Size

----------- ---------- -------------

2:01:0 Free 64.0KB:8.47GB

2:02:0 Free 64.0KB:8.47GB

2:03:0 Free 64.0KB:8.47GB

2:04:0 Free 64.0KB:8.47GB

To create a RAID-5 set, use the

container create raid5

command, as in the following example. In the example, a RAID-5 set
is created on SCSI devices (2,1,0), (2,2,0), and (2,3,0) using 100M
(megabytes) of freespace from each SCSI device. The /stripe_size
switch specifies that each stripe is 64K in size.

HPN0> container create raid5 /stripe_size=64K ((2,1,0), 100M)

(2,2,0) (2,3,0)

Executing: container create raid5 /stripe_size=65,536

((CHANNEL=2,ID=1,LUN=0),104,857,600) (CHANNEL=2,ID=2,LUN=0)

(CHANNEL=2,ID=3,LUN=0)

After running the

container create raid5

command, use the

container list

command to display information about the
