Isolating Problems
Isolating Library Power Problems
1. Ensure the power cord is plugged in at the power supply and at the electrical
outlet, then turn library power ON. Feel for air flowing out of the cooling fan
grill on the rear of the library. Power is good if air is flowing from the cooling fan
grill.
2. If power appears to be missing:
a. Plug the power cord into another electrical outlet.
b. Plug another device into the outlet to test.
c. If the outlet tests OK, try another power cord.
3. If you have verified that the electrical outlet and power cord works properly, but
the power supply is still failing, replace the library (see “Replacing the Library”
on page 8-13).
4. If the power supply seems to be delivering power to the library; however, air
does not flow from the power supply cooling fan grill on the rear of the library,
replace the library (see “Replacing the Library” on page 8-13).
Isolating Drive Problems
1. Ensure that the drive firmware is at the latest level (visit
http://www.ibm.com/
storage/
).
2. Cycle library power.
3. If the drive is experiencing permanent or temporary errors or if the Clean LED is
lit on the front panel of the library, clean the drive.
4. Run Library Verify .
a. If the test fails, replace the library.
b. If the test passes, run SAS Wrap Test .
i. If the test passes, resume normal library operations.
ii. If the test fails, replace the library.
Logs You are required to
download the library log or
drive log… Using the Web User Interface.

You need to acquire library
or drive information at the
host… See Appendix E, “Message Retrieval at the Host,” on page E-1.
Network Time
Protocol (NTP) The library time is not
being updated by the NTP
server… Using the Web User Interface.
1. Disable NTP.
2. Set the time manually.
3. Enable NTP.
Power If the power supply switch
is ON and the library is
OFF… See “Isolating Library Power Problems” on page 6-6.
Web User Interface HTML error 404 appears on
