Add a Module to an Existing Library
This procedure is designed for adding a module to the top of an existing library.
- Determine where your new EM unit will be in the rack. See Stackability for more specific details.
Installation Procedure
- Disconnect the power cables from the power source.
- Disconnect the power cables from the power supplies.
- Disconnect the Ethernet cable.
- Disconnect the SAS or Fibre channel cables from the drives.
There are two different versions of the top cover available on Scalar i3 systems, one with screws and one without screws.
Select from the options below:
-
Remove the magazines.
- If tapes are loaded in the magazine, mark the magazines so they can be placed back in their original bay.
-
Insert the T8 end of the assembly tool into the magazine release hole until the magazine pops out. Remove the magazine.
-
Using the empty magazine slots for access, use both hands to gently push up and forward on the inside of the top cover. This will release the top catch and side stops.
-
Slide the top cover off.
Required Tools: T-10 Torx Driver (included with library assembly tool)
-
Use the assembly tool to remove the 8 cover screws.
- Remove cover. Be careful not to let the cover sag in the middle or at the ends.
WARNING: The library will not operate properly if the spacers are not installed correctly.
-
Install the six (6) spacers in every module you plan to install, except the module you plan to put on top.
-
Install the spacers by pressing them down into the spacer slots in the chassis. With the flat side flush with the edge of the library, angle the spacer to get the outside edge in and then pinch the spacer near the clips to insert.
WARNING: Inserting the spacers straight down or using force to install them can cause slivers of plastic to fall into the module.
-
Place the module on top of the previously placed module.
-
Insert the “ear” of the rack mount clamp in one of the three slots on the side of the library. Choose the slot based on how much of the library you want to extend beyond the front and back of the rack. If your rack has a door, you want to make sure you can close the door when the library is mounted in the rack.
- Screw the 4 thumbscrews through the rack mount clamp slots into the threaded holes in the rack shelves.
Note: If you are adding the module to another module, don’t tighten the thumbscrews until you’ve aligned and attached the module. When the two alignment pins are down and the four module attachment screws have been tightened, tighten the rack thumbscrews.
Note: The images display yellow alignment pins. Newer modules have blue alignment pins.
-
Align the new module with the module below by eye.
-
Using the yellow/blue tab, slide the front alignment pin down into the hole on the module below.
- Using the yellow/blue tab, slide the rear alignment pin down into the hole on the module.
WARNING: Do not use the Module Interconnect to help align the modules. Work to get the alignment pins engaged before moving on to next steps.
There are two different version of the chassis available on the Scalar i3 system: a Series 1 chassis and Series 2 chassis.
Identify Your Chassis Series
- Series 1 - A Series 1 chassis uses screws to attach modules together.
- Series 2 - A Series 2 chassis contains latches on the front and rear of the chassis. These latches are used to attach modules together. A Series 2 chassis is backwards compatible with the Series 1 chassis.
-
To attach the module to the module below, use the two (2) long screws in the holes at the front of the module in the magazine bays.
Caution: Tighten using the Torx. Do not use the torque wrench.
-
To attach the module to the module below, use the two (2) short screws in the holes at the back of the module in the drive bay
-
Insert a short screw into the screw holder on the assembly tool.
-
Use the screw holder and the assembly tool torx wrench to get the rear screws started.
-
Pull straight back on the tool to release the screw.
-
Tighten the screw until you hear a click, or until you feel the torx wrench slip in the torque wrench. When it clicks or slips, the screw is torqued to 10 inch pounds.
-
If magazines are in the chassis, remove the magazines to access the front and rear latches in the chassis.
-
There are latches on the left and right front of the chassis. To lock, pull the latch towards the front of the chassis until it lifts and engages the front catch.
-
There are latches on the left and right rear of the chassis. To lock, push the latch forward until it moves down and engages the catch. A slot indicator on the side frame will also appear behind the latch when it is fully engaged into the catch.
Important Information - Bottom Module Latches
Do not lock the rear latches of the chassis containing the bottom cover in the module stack. The latches will interfere with tape drives being properly set into the chassis.
-
Pull out on the pin and slide the module interconnect up.
-
Tighten the rack thumbscrews on the module you just added.
Plug the power cord into the power supply. The library will begin start up operations.
- If available, connect the library to a DHCP server on your network with an Ethernet cable. If you are only using a single network connection, use Gb1 (Callout 1 below).
- Connect Fibre Channel drives with Fibre Channel cables. Connect SAS drives with SAS Mini HD cables (Callout 2 below)
- Plug the 90 degree connector into the primary power supply’s power connector (Callout 3 below)
- Plug the 90 degree connector into the redundant power supply’s power connector (Callout 4 below)
- Plug the primary power supply connector into a power source. The library will begin to initialize (Callout 5 below).
- Plug the redundant power supply connector into a power source. If possible, the redundant power supply should be connected to a power source on a different circuit (Callout 6 below).
IVT is a diagnostic test that verifies basic library functionality. It performs a complete library installation test to verify robotic operation within the current library configuration. IVT tests determine proper installation and operation by performing robotic self tests, by scanning tape cartridges, and performing GET/PUT tape cartridge tests at storage slot, I/E slot, and drive sled locations.
IVT uses existing tape cartridges for in-place GET/PUT testing, and moves a scratch tape to empty locations to verify proper slot and/or drive sled accessibility.
A complete IVT should be run as part of the installation process.
IVT Prerequisites
Review the following before running an IVT test:
- The library should have no unresolved RAS tickets.
- The library WebGUI accurately reflects the actual number of modules and drives in the system.
- The library is in a READY state all magazines are properly inserted.
- A scratch tape must be provided and placed into the first slot of the configured I/E area (Control Module's top right magazine, first column, bottom slot). If an I/E area is not configured, this slot position will be used by the library to locate the scratch tape, even if this slot is assigned as a storage slot to a partition.
-
Do Not use any cleaning tape as an IVT scratch tape. The IVT may fail due to timeout conditions.
- Do Not use an uncalibrated LTO-9 tape as an IVT scratch tape. If you do, the test will immediately fail and the drive will continue to calibrate the tape until it is complete. You will then need to manually remove the (now calibrated) tape and re-run IVT.
- If you do not have a calibrated LTO-9 scratch tape to run IVT, vary off the LTO-9 drives (see Vary Drive On or Off). This will prevent the test from failing due to LTO-9 calibration operations.
In addition to the prerequisites above, Quantum recommends that the scratch tape is read-capable by all drive generations in the library. If the tape cartridge media generation is not supported by a drive generation in the library, drive tests are skipped. The skipped drive tests will then need to be repeated with a scratch tape of compatible read format.
-
Press the right magazine release button on the Control Module (CM). The magazine will “pop” out. Pull the magazine until the first set of slots is exposed.
-
Insert a scratch tape. A scratch tape is a blank tape or one you don’t mind being overwritten. Insert the tape into the bottom front slot in the right magazine. This is the designated I/E slot for the library.
-
Select Diagnostics from the WebGUI menu.
- Select the Installation Verification Test checkbox from the North Panel.
-
Click the Test button in the Operation Panel. The Installation Verification Test window displays.
- The Complete IVT radio button should be pre-selected. If it’s not, select it.
-
Click Apply. The Progress area of the dialog window will display the test progress.
Note: You must wait until the library has finished initialization before you can begin the IVT process.
-
The results of each of the IVT tests displays in the Progress area.
Caution: The library will display a Ready status during IVT. Disregard and do not try and perform any library operations. When each Magazine Test is complete, the library will be ready.
