Conﬁguring into Your System a Partitioned

Disk Already Containing Data

NOTE This procedure is provided for conﬁguring a Series 800 legacy

hard-partitioned disk into HP-UX 10.0. Before proceeding, make sure

you have read “Planning to Conﬁgure into your System a Disk Already

Containing Data” and have performed the examination documented in

“Ensuring Against Clashes with HP-UX 10.0”.

Step 1. Before you move a disk from one system to another, you must create a

clear record of how the disk is set up on its original system. Make a

record of the following output:

• bdf, for information on what ﬁle systems are mounted.

• /etc/fstab, for information about the ﬁle systems mounted on the

disk at boot time. (If the disk is being moved from a 9.

system, the

equivalent ﬁle will have been called /etc/checklist. If the disk

being moved is partitioned, /etc/checklist will be your only source

of information for what partitions (sections) are being used.)

• swapinfo, for information on device and ﬁle-system swap space

enabled on the disk.

• If the disk is used for a database, make a record of the database

conﬁguration ﬁle.

Step 2. Back up the data on the disk; see the backup chapter in Managing

Systems and Workgroups.

Step 3. Create a record of your system's current disk conﬁguration for later

comparison:

/usr/sbin/ioscan -fun -C disk

Step 4. Note whether the current conﬁguration includes the device driver(s)

needed to communicate with the disk you intend to conﬁgure. Consult

the tables in “Selecting Device Drivers for a Disk Device and Interface”

for guidelines on compatible disks, device drivers, and interfaces. If any

necessary device driver is absent from the kernel, you will need to
