How to Remove and Replace a Drive in a L180/700/1400 Tape Library

Solution

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:(IS A SITE ENGINEER AVAILABLE?)

Trained on Lxxx Oracle/STK tape library.

TASK COMPLEXITY: 2

TIME ESTIMATE: 120 minutes

FIELD ENGINEER INSTRUCTIONS

PROBLEM OVERVIEW:

You can use "Drive Status" menu from operator panel (see "Drive Status" on page2-53) to check drive's status. Typically, drive failures are reported in this menu as:
-Not connected
-Unknown drive
-Not communicating
-Not functional
-Not loadable
Symptom Explanation Conditions That Could Cause This Issue
Client System:
-Cannot access a drive
-Marks drive unavailable
-Detects an unrecoverable error in drive
-Drive has lost power
-Poor or missing SCSI/fiber bus connection
-Defective SCSI/fiber cable
-Damaged tape
-Faulty drive

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? : Customer must place drive offline.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:
Refer to the StorageTek L180/700/1400 Service Manual, PN95846, for complete details on drive removal/replacement:

Note – Use VOP to capture the current drive configuration settings and force a diagnostic dump before you power down the drive tray.

Configuration Tasks - see KB 1947419.1

Before you power off the old drive

Before you power off the old drive you will want to save the current configuration from the drive. You will need to save the configuration to a file. The configuration screens are available in the Configure>Drive Data menu item. The drive must be Offline in order to access these screens.
The following screens contain configuration data:
i. Fibre
Use this tab to change tape drive-specific Fibre Channel/FICON configuration settings.
ii. ldsnmp
Use this tab to designate IP addresses for snmp managers.
iii. Logging
Use this tab to select which tape alerts are to be logged.
iv. Maintenance
Use this tab to enable or disable the Bias Re-optimization setting.
v. Network
Use this tab to change network configuration settings, including the IPv4 address and network node name.
Click Save Drive Config to save the current configuration data to a file.

Stay connected to the drive with VOP and force a diagnostic dump on the drive. See the next steps in this process.

NOTE:
Under NO circumstances should tape drives be returned with Media still inside the drive. If a tape is stuck in a drive, review the Knowledge Base or contact Tape Hardware Support for instructions on how to remove the tape with an email to tapehw_ww@oracle.com include the SR/case number in the subject line of the email.

Tape Drive Removal / Replacement when dWWN Enabled:

Caution:
Fiber fabric problems:  Read the information below before removing or replacing a Fibre Channel drive in a library that has dynamic World-Wide Naming enabled.

The dynamic world-wide naming feature assigns names to Fibre Channel drives by their slot location in a drive tower rather than by their drive number.  The dWWN feature allows you to replace a Fibre Channel drive without the need to re-configure the network.

The Action Plan steps listed below apply to T10000, 9840, 9940, LTO (IBM and HP), and SDLT drives. Additional details may be called out for a specific drive type, if applicable.

NOTE: Prior to replacing LTO drive verify the same PN is used.  This is to avoid problems with 2 and 4 GB drives being interchanged.  HP drives have different code for 2 and 4 GB drives.  IBM does not.

Drive Removal:
When removing a drive in a library that has dWWN enabled, you must determine:
- If the drive is to be left on site and if there is a possibility that the drive will later be connected in a non-dWWN environment.
- If the drive may be used in another library that does not contain 3.02 or later firmware.

In either of these situations:
1. Make sure that the drive is unavailable to the system.
2. Disconnect the Fibre Channel cable from the drive.
3.Connect your laptop to the CLI port.

Caution:
Fiber fabric problems:  Be sure that the "pprrcc" in the next step is correct; if the wrong drive value is entered, you may have to re-configure the system.

4. Enter DRIVE PPRRCC PEVERT, where "pprrcc" is the panel, row, and column of the drive.  The "revert" command will cause the drive to revert to its native value.
   a. If the drive is to be returned to the factory, power off the drive and pack the drive for return shipment.
   b. If the drive is not functional enough to revert, make a note of this fact in the return shipment.

Drive Replacement:
When replacing a drive in a library that has dWWN enabled:
- If the drive is dWWN-compatible:
     Replace the drive.
     Power on the drive.
     Wait until the operator panel notifies you that the drive configuration is completed.
     (That is, until the Op Panel no longer indicates "configuring" on the initial status screen).
     Connect the Fibre Channel cable.
- If the drive is downlevel (the operator panel displays CONFIGURING continuously):
     Upgrade the drive to the supported dWWN firmware level.
     Wait until the operator panel notifies you that the drive configuration is completed.
     (That is, until the operator panel no longer indicates "configuring" on the initial status screen).
    Connect the Fibre Channel cable.

NOTE: Under NO circumstances show tape drives be returned with Media still inside the drive. If a tape is stuck in a drive, do a knowledge search for tape removal instructions or contact the Tape Hardware Support for instructions on how to remove the tape. Use a collaboration SR and assign to the Tape Hardware group.

Recovery information:
Drive, library, and system recovery from the hot swap procedure is explained below.
Once the drive is replaced:
-SCSI "Bus Reset" command is not asserted during the operation
-Library senses that new drive is installed
-Library communications with drive is automatically resumed
-SCSI ID of drive is automatically assigned same ID of drive that was replaced---no reconfiguration or library re-boot is required.
-Drive type, SN & FW version is automatically updated.
-Drive handle is cycled (DLT only)
-Drive is automatically available to library.
-Some system intervention may still be required to make drive available

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Have customer bring drive back on line.

PARTS NOTE:
