1. Select one or more partitions on the SANnet II 200 that you want to use. The output of
ioscan
(1M) shows the disks attached to the system and their device names:
2. Initialize each partition as an LVM disk with the
pvcreate
command. For example,
enter:
Caution –
This process results in the loss of any data that resides on the partition.
I.7 Creating a Volume Group
The volume group contains the physical resources that you can use to create usable
storage resources for your applications.
1. Create a directory for the volume group and a device file for the group in that
directory:.
The name of the directory is the name of the volume group. By default, HP-UX uses
names of the format
vg
NN
,
but you can chose any name that is unique within the list
of volume groups.
In the preceding example the
mknod
command has the following arguments:
■
The fully qualified pathname of the new device file
group
■
The letter
c
indicates a character device file
■
The major number 64 (used for all volume groups)
■
A minor number of the form
0x
NN
0000
, where NN is the two-digit hexadecimal
representation of the volume group number (06 in the example)
