Installation guide
Mirror capacity: single mirrored
Disk type: rz56
Use the following example as a guide for migrating your ULTRIX shadowed
data:
1. Dump the ULTRIX shadowed file system to tape by entering the
following command on your ULTRIX system:
# dump 0uf /dev/rmt0h /fs
This command copies the entire contents of the /fs file system to the
/dev/rmt0h tape. The command also records the date of the dump in
the file /etc/dumpdates when the dump is successful.
2. On the DIGITAL UNIX system, create a label on the disks you will use
for mirroring:
# disklabel -r -w rz1 rz56
# disklabel -r -w rz2 rz56
These commands install the standard label on the designated drive.
(For more information about initializing disks, see the System
Administration manual.)
You can omit this step if you have already installed a label on your
disks.
3. On the DIGITAL UNIX system, create and extend a nonmirrored
logical volume using the following steps:
a. Create the physical volumes you will use for disk mirroring by
entering the LVM pvcreate command:
# pvcreate /dev/rrz1g
Physical volume /dev/rrz1g has been successfully created.
# pvcreate /dev/rrz2g
Physical volume /dev/rrz2g has been successfully created.
This command initializes your direct access storage device for use
as a physical volume in a volume group.
b. Create a volume group directory in the /dev directory:
# mkdir /dev/vg01
Volumes that are mirrored must be in the same volume group.
This command creates the directory that identifies the volume
group vg01 for the LVM subsystem.
c. Create the volume group device file:
# mknod /dev/vg01/group c 16 0
