Drive Replacement

Use this procedure to replace a tape drive in a Scalar i6000 library.

If a drive fails, the library will issue a RAS ticket. From the RAS ticket, write down the Repair Link or Error Code number.

WARNING:

Before performing any of the steps listed in this document, contact Quantum Service for help diagnosing the problem.
To use this procedure, all drives must be connected to an Ethernet Expansion Blade (EEB) or an FC I/O blade.

Before You Begin

Important Information - Drive Acclimation

Before opening the sealed ESD bag, the drive should be acclimated to the climate inside the facility or room location where the drive will be installed. Changes in temperature and humidity can cause condensation. It is recommended to leave drives in the packaging for a minimum of 24 hours before opening the sealed bag.

Place the sealed bag away from direct sources of air convection to minimize condensation.

If any external or internal condensation is seen on the sealed bag after 24 hours, remove the drive from the bag and acclimate the drive in the planned location for an extra 12 to 24 hours, or until no visible condensation remains.

Figure 1: Drive in Sealed Bag

Once the bag has been opened, the drive should never be moved to a new location where temperature differences are greater than 5 degrees Celsius. If this type of drive relocation needs to occur, the drive should be placed in a sealed bag with desiccant and allowed to acclimate to the new location for a minimum of four hours.

Figure 2: Drive with Dessicant

Drive temperature and humidity specifications are as follows:

Note: The temperature and humidity specifications below are for LTO drives. For LTO media temperature and humidity specifications, refer to the Environmental Specifications in the Site Planning Guide.

Mode	Air Inlet Temperature	Relative Humidity (Non-Condensing)	Altitude (Max)
Operating Mode	10°C to 40°C (50°F to 104°F)	20% to 80% 26°C (79°F) Wet Bulb Max	3048 m
Recommended Operating Mode	20°C to 25°C (68°F to 77°F)	40% to 50%	3048 m
Storage	-40°C to 60°C (-40°F to 140°F)	10% to 90% Non-Condensing	3048 m
Shipping	-40°C to 60°C (-40°F to 140°F)	10% to 90% Non-Condensing	12192 m

Locating a Drive

When a drive fails, a RAS ticket is generated by the library that will identify the malfunctioning drive using a coordinate system. This section will explain the basics of locating a drive using the coordinate system so when you are replacing the drive, you will be able to identify the correct drive. Removing a drive incorrectly can impact data on your library.

The drive coordinate system has five (5) numbers. In the example below, we are going to locate a drive with the coordinates 1,1,11,1,1 in a library that is configured with the following:

1 Left Parking Module (LPM)
1 Control Module (CM)
4 Expansion Modules (EM)
1 Right Parking Module (RPM)

Item	Name
1	Left Parking Module (LPM)
2	Control Module (CM)
3	Expansion Modules (EMs)
4	Right Parking Module (RPM)

Important Information: 6 Drive Number Coordinates

In the LMC and some RAS tickets there will be 6 coordinate numbers. The first number in a six number coordinates is the aisle number and will always be one. Disregard this number and read the next 5 numbers in the drive coordinate. For example, a coordinate that is displayed as 1,1,1,1,2,1 in the LMC or RAS ticket should be read as 1,1,1,2,1.

The first number in the sequence identifies the module. The module number can be from 0-19. This applies to both single- and dual-robot libraries. The left parking module (module 0) is only for dual-robot libraries and cannot contain drives. A high-density expansion module (HDEM) also cannot contain drives.

A maximum of 18 drives can be installed in each control module (CM) and a DREM can contain a maximum of 24 drives

The second number in the sequence represents the rack. Since drives can only be contained in rack 1, this number will always be 1.

The third number in the sequence indicates the section. Each control module can contain 18 drives so with drives, this number can range from 1-12 in each column. Drives are counted from bottom to top.

The fourth number in the sequence identifies the column. Since drives can only be contained in a single column, they will always reside in column 1 or 2.

The fifth number in the sequence denotes the row and will always be 1. Drives have a connection point at the lower portion of the drive sled that connects to the library. Therefore, the sled is logically in row 1.

Remove and Replace the Drive

This procedure is used to replace a drive with the same drive model. Drive upgrades must be performed by Quantum service personnel. If the failed drive is an EDLM drive, it must be replaced by Quantum service personnel.

Caution: Before starting this procedure, verify that you have received the same make and model drive as the drive you are replacing. The outside of the box will indicate the drive make and model that was shipped.

Required tool: Phillips screwdriver - use this if the thumbscrews are too tight.

Remove and Replace Drive Using the Library Management Console (LMC)

Update the Drive Firmware

Important Information

This procedure should only be used if drive auto-leveling is turned off.
If you are viewing a partition, drive firmware update operations affect drives that are within the partition only.
You can only perform firmware updates for drives of the same product, such as IBM LTO-4 or HP LTO-5.
If you load a firmware image onto a drive that is the same version that is currently running on the drive, the upgrade will fail.
The appropriate drive firmware image must be uploaded to your library prior to beginning the update process (see Update or Remove Drive Firmware).

Federal Information Processing Standard (FIPS) Firmware

FIPS firmware is indicated by _f and (FIPS) in the firmware name.

FIPS firmware example - IBM_LTO7_H9E2.fcp_fh_f.fmrz (FIPS)
Non-FIPS firmware example - IBM_LTO7_G9Q4_fcp_fh.fmrz
Drives in a FIPS partition cannot have non-FIPS firmware loaded.

Upgrade Drive Firmware Using LMC

From the View menu, select the partition that contains the replacement drive.
Select Tools > Update Software > Drives. A warning dialog box displays stating the partition needs to be taken offline.
