Adding a Disk Drive
The internal disk drives (A upper and B lower) are located in the back of
the SPU. The internal disk drives are hot swapable when the proper
software and hardware procedures are followed.
To add a disk drive in the SPU, perform the following hardware steps:
1. Align the new disk drive into the disk tray and insert the four (2 on
each side) mounting screws to secure the disk to the tray.
2. Align the disk and tray assembly to the empty slot in the back of the
SPU.
3. Carefully slide the disk into the SPU until it firmly seats into the disk
card. Note that the guide tabs on each side of the disk tray fully seat
to the guide pins on the chassis.
4. Angle the bottom of the disk cover plate into the SPU so that the
hooked tabs go over the extended pins inside the chassis. This acts
like a hinge for the cover.
5. Push the top of the cover plate towards the SPU until it is flush with
the chassis and fully seated.
6. Tighten the single, captive mounting screw.

Once you have completed the addition of the disk drive, you must
perform the Hot swap procedure:
Hot Swap Software Procedure
NOTE HP often uses different manufacturers for disks having
the same product number. This hot swap procedure will
not automatically update the disk driver’s internal
manufacturer information to that of the added disk drive.
Step 1. Do an ioscan on the added disk drive to ensure that it is
accessible an also as a double check that it is a proper
installation. Refer to the above note. For example:
# ioscan /dev/dsk/cXtXdX
Step 2. Create a physical volume using pvcreate with the -B option. -B
creates an area on the disk for a LIF volume, boot utilities, and
a BDRA (Boot Data Reserved Area). For example,
# pvcreate -B /dev/rdsk/cXtXdX
Step 3. Create a directory for the volume group using mkdir.
Step 4. Create a device file named group in the above directory with
the mknod command.
Step 5. Create the root volume group specifying each physical volume
to be included using vgcreate. For example:
vgcreate /dev/vgroot /dev/dsk/cXtXdX
Step 6. Use mkboot to place boot utilities in the boot area:
mkboot /dev/rdsk/cXtXdX
Step 7. Use mkboot -a to add an AUTO file in boot LIF area, for
example:
mkboot -a ‘’hpux (52.3.0;0)/stand/vmunix’’
/dev/rdsk/cXtXdX
Step 8. Create the root logical volume. You must specify contiguous
extents (-C y) with bad block relocation disabled (-r n). For
example,

3
lvcreate -C y -r n root /dev/vgroot
Step 9. Extend the mirrors onto the disk you’ve added. For example:
lvextend -m 1 <LV name> /dev/vgroot/root /dev/dsk/cXtXdX
Step 10. Specify that logical volume be used as the root logical volume,
for example:
lvln -r /dev/vgroot/root
At this point you will need to create a file system on the disk. Refer to
your HP-UX system administration documentation.
Hot Swap Procedure for Unattached Physical Volumes
Follow these steps to replace a hot swap disk drive for unattached
physical volumes.
NOTE HP often uses different manufacturers for disks having
the same product number. This hot swap procedure will
not automatically update the disk driver’s internal
manufacturer information to that of the added disk drive.
Step 1. Do an ioscan on the replaced disk drive to ensure that it is
accessible an also as a double check that it is a proper
replacement. Refer to the above note. For example:
# ioscan /dev/dsk/c2t4d0

Step 2. Create a physical volume using pvcreate with the -B option. -B
creates an area on the disk for a LIF volume, boot utilities,
and a BDRA (Boot Data Reserved Area). For example:
# pvcreate -B /dev/rdsk/cXtXdX
Step 3. Create a directory for the volume group using mkdir.
Step 4. Create a device file named group in the above directory with
the mknod command.
Step 5. Create the root volume group specifying each physical volume
to be included using vgcreate. For example,
# vgcreate /dev/vgroot /dev/dsk/cXtXdX
Step 6. Use mkboot to place boot utilities in the boot area:
# mkboot /dev/rdsk/cXtXdX
Step 7. Use mkboot -a to add an AUTO file in boot LIF area, for
example:
# mkboot -a ‘’hpux (52.3.0;0)/stand/vmunix’’
/dev/rdsk/cXtXdX
Step 8. Create the root logical volume. You must specify contiguous
extents (-C y) with bad block relocation disabled (-r n). For
example,
# lvcreate -C y -r n root /dev/vgroot
Step 9. Attach the new disk drive to the active volume group with the
vgchange command.
# vgchange -a y <volume group name>
For example:
# vgchange -a y /dev/vg00
Step 10. After running the mkboot command, do an lvlnboot -R to link
the added disk drive into the boot data reserved area of all the
physical volumes in the volume group.
# lvlnboot -R
Step 11. Create mirrors on the disk you’ve added. For example,

5
lvextend -m 1 <LV name> /dev/vgroot/root /dev/dsk/cXtXdX
Step 12. Synchronize the mirrors. This may take several minutes as it
will have to copy all the data from the original copy of the data
to the mirrored extents. The logical volume(s) are still
accessible to users’ applications during this command.
#vgsync <VG name>
For example:
#vgsync /dev/vg00
At this point the system should be fully functional.

Adding a Power Supply
Before unpacking the new power supply, inspect the shipping carton for
obvious damage. If damage to the shipping carton is observed, report it to
the carrier immediately.
Carefully unpack the new power supply. Check it for damage. If no
damage is observed, proceed with the instructions that follow. If damage
is noticed, do not install the power supply. Get a replacement power
supply.
WARNING Be careful lifting the power supply into the SPU, it
weights approximately 7.88 Kg (17.5lbs.).
WARNING The AC power to the SPU does not have to be
disconnected to add a power supply to the SPU. Also
the power switch on the SPU does not have to be in
the standby position to perform this task.
To add a power supply in the SPU, perform the following steps:
1. Be sure the power switch on the power supply is in the OFF position.
2. Removethe frontbezel.
3. RemovetheEMI shield.
4. Remove the power supply slot cover in the desired position, by
loosening the two captive screws at the top edge of the cover, then pull
it away from the SPU.
5. Align the power supply with the selected empty slot in the front of the
SPU.
6. Slide the power supply into the SPU while holding the
insertion/extractor lever out (horizontal).

7. Push the power supply into the SPU firmly until the
insertion/extractor lever can hook under the extended tab on the SPU.
8. Push the insertion/extractor lever down, flush with the power supply.
This firmly seats the power supply to the system board.
9. Tighten the two captive mounting screws.
10.Be sure the power cord associated with the power supply installed is
connected at the back of the SPU.
11.Put the power switch, on the front of the power supply, in to the ON
position.
NOTE The power OK LED should be on when the power switch is
in the ON position, and there is a power cord plugged
in.
12.Replace the EMI shield by inserting the tabs on the top of the EMI
shield into the slots chassis just below the front panel. Then push the
EMI shield into the chassis and tighten the two mounting screws on
the bottom.
13.Replace the front bezel by aligning it over the front panel and front of
the chassis and snapping it to the bezel retainer clips along the sides

of the chassis.
Once the system is re-assembled, be sure there are no errors on the front
panel or system console. Be sure the system is ready for customer use.
