CAUTION: Regarding IBM provided VENDOR LIFT TOOL:

v Operation of LIFT TOOL by authorized personnel only. v LIFT TOOL intended for use to assist, lift, install, remove units (load) up into rack elevations. It is

not to be used loaded transporting over major ramps nor as a replacement for such designated tools like pallet jacks, walkies, fork trucks and such related relocation practices. When this is not practicable, specially trained persons or services must be used (for instance, riggers or movers).

v Read and completely understand the contents of LIFT TOOL operator's manual before using.

Failure to read, understand, obey safety rules, and follow instructions may result in property damage and/or personal injury. If there are questions, contact the vendor's service and support. Local paper manual must remain with machine in provided storage sleeve area. Latest revision manual available on vendor's web site.

v Test verify stabilizer brake function before each use. Do not over-force moving or rolling the LIFT

TOOL with stabilizer brake engaged.

v Do not move LIFT TOOL while platform is raised, except for minor positioning. v Do not exceed rated load capacity. See LOAD CAPACITY CHART regarding maximum loads at

center versus edge of extended platform.

v Only raise load if properly centered on platform. Do not place more than 200 lb (91 kg) on edge of

sliding platform shelf also considering the load's center of mass/gravity (CoG).

v Do not corner load the platform tilt riser accessory option. Secure platform riser tilt option to main

shelf in all four (4x) locations with provided hardware only, prior to use. Load objects are designed to slide on/off smooth platforms without appreciable force, so take care not to push or lean. Keep riser tilt option flat at all times except for final minor adjustment when needed.

v Do not stand under overhanging load. v Do not use on uneven surface, incline or decline (major ramps). v Do not stack loads. v Do not operate while under the influence of drugs or alcohol. v Do not support ladder against LIFT TOOL. v Tipping hazard. Do not push or lean against load with raised platform. v Do not use as a personnel lifting platform or step. No riders. v Do not stand on any part of lift. Not a step. v Do not climb on mast. v Do not operate a damaged or malfunctioning LIFT TOOL machine. v Crush and pinch point hazard below platform. Only lower load in areas clear of personnel and

obstructions. Keep hands and feet clear during operation.

v No Forks. Never lift or move bare LIFT TOOL MACHINE with pallet truck, jack or fork lift. v Mast extends higher than platform. Be aware of ceiling height, cable trays, sprinklers, lights, and

other overhead objects.

v Do not leave LIFT TOOL machine unattended with an elevated load. v Watch and keep hands, fingers, and clothing clear when equipment is in motion. v Turn Winch with hand power only. If winch handle cannot be cranked easily with one hand, it is

probably over-loaded. Do not continue to turn winch past top or bottom of platform travel. Excessive unwinding will detach handle and damage cable. Always hold handle when lowering, unwinding. Always assure self that winch is holding load before releasing winch handle.

v A winch accident could cause serious injury. Not for moving humans. Make certain clicking sound

is heard as the equipment is being raised. Be sure winch is locked in position before releasing handle. Read instruction page before operating this winch. Never allow winch to unwind freely. Freewheeling will cause uneven cable wrapping around winch drum, damage cable, and may cause serious injury. (C048)

Resolving an operating system boot failure

Learn how to identify the service action that is needed to resolve a failure while you boot the operating system.

1. Was the system recently installed, serviced, moved, or upgraded?

If Then Yes: Ensure that all cables are properly seated in the connection path to the designated boot

device. This ends the procedure.

No: Continue with the next step.

2. Are you booting the operating system from a network location?

If Then Yes: Continue with the next step. No: Continue with step 4.

3. Complete the following actions, one at a time until the problem is resolved: a. Ensure that a problem does not exist with the connection to the network location. b. Ensure that the adapter has a valid IP address for the network. c. Replace the network adapter. To identify the physical location and the removal and replacement

procedure, see “7063-CR1 locations” on page 37.

4. Petitboot displays all recognized bootable images to use by default. Is the boot image recognized by Petitboot?

If Then Yes: Continue with step 15 on page 7. No: Select the Petitboot menu option to refresh boot images. If the problem persists, continue

with the next step.

5. From the Petitboot menu, select Exit to shell. Is the mvcli utility already installed?

If Then Yes: Continue with step 7 on page 7. No: Continue with the next step.

6. Install the mvcli utility. For more information about installing the mvcli utility, go to mvCLI commands. Then, continue with the next step.

7. If you obtained the mvcli utility from a USB drive that is inserted into one of the USB ports of the

system, type /tmp/media/mvcli. Otherwise, type /tmp/mvcli.

8. To check the status of the RAID virtual disk, type info -o vd and press Enter. To check the status of

the physical disks, type info -o pd and press Enter. The output indicates the status of the drive. Is the boot drive recognized and in optimal status?

If Then Yes: Reinstall the operating system on the boot drive. This ends the procedure. No: Continue with the next step.

9. Are the drives properly seated in their respective drive bays?

Note: To identify the physical location and the removal and replacement procedure, see “7063-CR1 locations” on page 37.

If Then Yes: Continue with the next step. No: Properly seat the drives in the drive bays. Then, go to step 4 on page 6.

10. Refresh the Petitboot boot options. Is the boot image on the boot drive recognized?

If Then Yes: Boot the operating system. Then, continue with step 15. No: Continue with the next step.

11. From the Petitboot menu, select Exit to shell.

12. If you obtained the mvcli utility from a USB drive that is inserted into one of the USB ports of the

system, type /tmp/media/mvcli. Otherwise, type /tmp/mvcli.

13. To check the status of the RAID virtual disk, type info -o vd and press Enter. To check the status of

the physical disks, type info -o pd and press Enter. The output indicates the status of the drive. Are the drives that are known to be in the virtual drive recognized?

If Then Yes: Reinstall the operating system on the boot drive. This ends the procedure. No: Continue with the next step.

14. Complete the following actions, one at a time until the physical drives are recognized in the virtual

drive:

Note: To identify the physical location and the removal and replacement procedure, see “7063-CR1 locations” on page 37.

a. If the drive is connected directly to the system backplane, ensure that the SATA cables are

properly seated in the disk drive backplane and in the system backplane.

b. Replace the SATA cable. c. If the drive is connected directly to the system backplane, replace the system backplane.

This ends the procedure.

15. Does an operating system error occur during the boot?

If Then Yes: Recover the operating system by using the tools for the operating system. If that does not

resolve the problem, reinstall the operating system. This ends the procedure.
