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,

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,

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.
