Installing the external tape drive

For IR R2.0, the only external tape drive that is supported is the Sun StorEdge DAT 72 Tape Drive.

To install the Sun StorEdge DAT 72 Tape Drive with the Sun Fire V240 platform or the Sun Fire 280R platform, perform the following steps:

1. Unpack the contents of your drive package.

   CAUTION: Static electricity can damage the components of your tape drive. Always wear an antistatic wriststrap if possible. If it is not possible to wear an antistatic wriststrap, to equalize the electromagnetic charges, touch a bare metal part of the server (such as the back plate) before you remove the tape drive from its bag.

2. Perform a normal Avaya IR system shutdown and turn off the Avaya IR system and any connected peripherals.
3. Connect your Sun StorEdge DAT 72 external tape drive to the external SCSI interface of the required platform. Connect the power connectors of your tape drive. For more information, see Sun Fire V210 and V240 Servers Installation Guide and Sun Fire 280R Server Service Manual.

   Note: Your SCSI interface cable is not shipped with the IR system, and should be provided when you purchase your Sun StorEdge DAT 72 external tape drive

4. Turn on your IR system and your tape drive. Your tape drive is turned on when the LED on the front panel of the tape drive glows.
5. Log in to the IR system with root permissions..
6. At the command prompt, enter ls /dev/rmt to list the any existing raw tape devices.
7. Enter devfsadm to load every driver in the system and attach to all possible device instances. After this command has been executed, your IR system should detect the presence of your tape drive

   Note: This command may take some time to execute.

8. Enter ls /dev/rmt to ensure your Sun StorEdge DAT 72 external tape drive is listed. the output of the ls /dev/rmt command is displayed on the screen as shown below.

   irv240dev4(root)# ls /dev/rmt

   0 0b 0bn 0c 0cb 0cbn 0cn

   0h 0hb 0hbn 0hn 0l 0lb 0lbn

   0ln 0m 0mb 0mbn 0mn 0n 0u

   0ub 0ubn 0un

   All these names listed above refer to the first tape drive connected to the system, and these names have a prefix of "0". If this is the second drive connected to the system, then the names have a prefix of 1n.

   Note: If after running the "devfsadm" /dev/rmt command, the result does not display the tape drive listing, then the SCSI connector is probably faulty, or not connected properly. Reconnect the SCSI connector and retry the "devfsadm" command.

9. Enter mt -f/dev/rmt/0n command to check the status of the tape drive. In this command, 0n denotes the tape drive being use.

   There are 5 possible outputs, to the command used above:

   1. irv240dev4(root)# mt -f /dev/rmt/0n status

      HP DAT-72 tape drive:

      sense key(0x0)= No Additional Sense residual= 0 retries= 0

      file no= 4 block no= 0

      In this case, since the value of the sense key = No Additional Sense, the tape drive is ready.

   2. irv240dev4(root)# mt -f /dev/rmt/0n status

      HP DAT-72 tape drive:

      sense key(0x6)= Unit Attention residual= 0 retries= 0

      file no= 0 block no= 0

      In this case, since the value of the sense key = Unit Attention, the drive is ready. It is similar to the first case, but here, either the drive has been activated for the first time, or is being operated after a long time, or is being operated after a system reset.

   3. irv240dev4(root)# mt -f /dev/rmt/0n status

      /dev/rmt/0n: Device busy

      In this case, the drive is busy. It is carrying out an operation like read, write, rewind, forward, etc. You should retry the command after some time, when the current system operations have ended.

   4. irv240dev4(root)# mt -f /dev/rmt/1n status

      /dev/rmt/1n: No such file or directory

      In this case, an incorrect device name has been used. (/dev/rmt/1n). Retry using the correct name.

   5. irv240dev4(root)# mt -f /dev/rmt/0n status

      /dev/rmt/0n: no tape loaded or drive offline

      In this case, the drive does not have any cartridge.

To install the Sun StorEdge DAT 72 Tape Drive with the Sunblade 150, perform the following steps:

1. Unpack the contents of your drive package.

   CAUTION: Static electricity can damage the components of your tape drive. Always wear an antistatic wriststrap if possible. If it is not possible to wear an antistatic wriststrap, to equalize the electromagnetic charges, touch a bare metal part of the server (such as the back plate) before you remove the tape drive from its bag.

2. Perform a normal Avaya IR system shutdown and turn off the Avaya IR system and any connected peripherals.
3. Install a SCSI interface card in the PCI card slot. For more information, see Sun Blade 150 Getting Started.

   Note: Your SunBlade 150 system does not have an external SCSI interface.

4. Connect the SCSI cable and power connector from the required platform to the back of the tape drive.
5. Turn on your IR system and your tape drive. your tape drive is turned on when the LED on the front panel of the tape drive glows.
6. Log in to the IR system with root permissions..
7. At the command prompt, enter ls /dev/rmt to list the any existing raw tape devices.
