Back up the data on the disk being configured
into the system; see the backup chapter in Managing Systems
and Workgroups. Create a record of the system's current disk configuration
for later use: /usr/sbin/ioscan -fun -C disk |
Note whether the current configuration includes the device
driver needed to communicate with the disk you intend to configure.
Consult “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 rebuild the kernel to include it. Here is how you
rebuild the kernel: Change
directory to the build environment (/stand/build). Execute a system preparation script,
system_prep, which extracts the system file from the current
kernel and writes a system file in your current directory. (That is, it creates
/stand/build/system.) The -v gives verbose explanation as the script executes. cd /stand/build
/usr/lbin/sysadm/system_prep -v -s system |
Modify the /stand/build/system file to add the absent driver(s) by invoking the kmsystem command. The -c Y specifies that driver-name is to be configured
into the system. /usr/sbin/kmsystem -S /stand/build/system -c Y driver-name |
| | | |  | NOTE: To avoid introducing format errors, do not edit the
HP-UX system description files directly. Instead, use the commands kmsystem and kmtune. These commands are new for Release 11.0; consult kmsystem(1M) and kmtune(1M) in
the HP-UX Reference. | | | | |
Build the new kernel by invoking the mk_kernel command. This creates /stand/build/vmunix_test, a kernel ready for testing. /usr/sbin/mk_kernel -s /stand/build/system |
Save the old system file by moving it. Then move the
new system file into place. mv /stand/system /stand/system.prev
mv /stand/build/system /stand/system |
Prepare for rebooting by invoking the kmupdate command. This sets a flag that tells the system
to use the new kernel when it restarts.
Bring the system down and physically install the disk
device. Turn on the power to all peripheral devices. Wait for
them to become "ready", then turn on power
to the SPU. On booting up, HP-UX detects the new disk and associates
it with its device driver. insf creates the character and block device special
(/dev) files required to communicate with the disk. Execute /usr/sbin/ioscan
-fun -C disk again, to identify the newly configured disk device
and its device special files.
