Pre-call checklist

If you have questions or problems with the library, complete these steps before a call to IBM technical
support is placed.

1. If you suspect the tape drive needs to be replaced, first go to the section called READ and FOLLOW
before replacing drives
110 IBM TS4300 Tape Library Machine Type 3555: User's Guide
Solution
• Run the Encryption Connectivity Check or Key Path Diagnostics and review
the results message. See "Locating Management functions" on page 79.
• Validate that the server configuration properties file includes support for TLS
1.2. See the encryption server documentation.
• If SKLM v2.7 or higher is used and you're using the Library Self-Signed
Certificate. For one time only, you might need to reset your encryption
settings to clear out old versions of the self-signed certificate, reconfigure
encryption, then accept the new self-signed certificate on the encryption
server. See "Configuring Library Managed Encryption" on page 88.
• Check that your certificate algorithm is supported by your version of the
server.
Note:
• The tape drive must rewind the tape before it is ejected. The amount of
time for this procedure can vary, depending on how the tape was used. See
"Supported tape drives" on page 10.
• The tape drive performs media optimization on the first load of a cartridge.
The amount of time for this procedure can vary. See "Supported tape drives"
on page 10.
The procedure for SCSI timeouts varies depending on whether timeout is
consistent or intermittent, and on your drive configuration. Follow these steps
to troubleshoot a SCSI timeout:
1. Stop all Host Activity.
2. Check drive status by using any of the following methods:
• SCD display
• ITDT
• Indicator lights on a library if the drive is installed in a library
3. If the drive is in the middle of performing an operation, wait until the drive
is idle before attempting any further steps.
4. Validate that the drive has the latest firmware.
5. Check with software application provider for any updates.
6. Check whether the tape drive power is on.
7. Power down the drive.
8. Verify that the SAS or FC cable is connected properly to the server and to
the tape drive.
9. Replace SAS or FC cable if it shows any signs of damage.
10. Power on the drive and wait until the tape drive is idle or ready.
