v Yes: Continue with the next step.
v No: Go to step 25 (See page 142).
24.
Does the system continue normal operation in 3 to 4 minutes?
v No: Go to step 26 (See page 142).
v Yes: Go to step 28 (See page 142).
25. When the 9337 Disk Unit Data display contains the value B000, the disk unit has reached a ready
status, but the system has not taken the ready status messages.
Does the 9337 Disk Unit Data display contain the value B000 in less than 4 minutes?
v Yes: Continue with the next step.
v No: Use the service information for the specific disk unit to analyze the status of the failing unit.
This
ends the procedure.
26. Perform the following:
a. Check the cable connections between all of the units on the storage device I/O processor card
that is connected to the failing unit.
b. Correct any loose connections and ensure that the terminating plug is installed tightly.
c. Check the address switches on the backs of all of the units connected to the magnetic storage I/O
processor card that is connected to the failing disk unit.
Notes:
1) If the device does not have address switches, continue with the next step of this procedure if
you are servicing one of these units.
2) Ensure that each address switch displays the correct number. See the system configuration
list. The latest level printout should be stored, ask the customer for this data.
d.
If two or more address switches display the same number, change the address number of one or
more units so that each address switch displays the correct number (see the system configuration
list).
e. For each unit that had its address switch changed, set the unit Power switch off, then on again.
27.
Does the system continue normal operation in 3 to 4 minutes?
v No: Set the Power switch on the disk unit to the Off position, then to the On position.
Does the system continue normal operation in 3 to 4 minutes?
– Yes: Continue with the next step.
– No: Go to step 29 (See page 142).
v
Yes: Continue with the next step.
28. Intermittent equipment checks may have caused this problem.
Display the system product activity log and look for entries that contain unit reference codes or IOP
reference codes that may need action.
You can read a unit reference code history from the disk controller service panel.
This ends the procedure.
29. Fill out a Problem summary form using the information from words 1 through 9 from the control panel.
Are characters 5-8 of the top 16 character line of function 11 (4 rightmost characters of word 1) on
the Problem Summary Form the same as on the Problem Summary Form filled out in step 3 (See
page 138)?
v Yes: Continue with the next step.
v No: A different SRC or reference code occurred. Use the new SRC or reference code to correct
the problem (see System Reference Codes).
This
ends the procedure.
30.
Are words 3 - 9 on the Problem summary form the same as on the Problem Summary Form filled out
in step 3 (See page 138)?
v Yes: Continue with the next step.
