If an SRC is displayed, perform the procedure indicated by the SRC. If the IPL is not successful, go to
step 2 on page 1-6. If the IPL is successful, run system test to verify that the problem is fixed. Go to
"328 Service Procedures under SSP" on page 3-10.
2. Reload the SSP diskettes to disk drive A and perform an IPL from disk. See the following:
a. Reference procedure "322 Reloading the SSP Diskettes" on page 3-8.
If an SRC is displayed or if the IPL is not successful, continue with the next action. If the IPL is
successful, run system test to verify that the problem is fixed. Go to "328 Service Procedures under
SSP" on page 3-10.
Notes:
a. The customer's data will be destroyed when you initialize the disk. To minimize the exposure of
destroying customer data, read the following note.
b. An alternative method to initializing disk drive A is to install a new disk drive before performing step
3. If the new disk drive fails, use the list of FRUs at the end of this procedure to isolate the
problem. It may be necessary to reinstall the old disk drive and attempt to initialize the disk to
remove customer data.
3. Initialize disk drive A, reload the system microcode to disk, reload the SSP diskettes to disk, and perform
an IPL.
a. Insert diskette 61 in the 5363 diskette drive. Perform an IPL of the 5363 using a select function 3,
enter a code of 22FF, and press the Start Function key.
b. Select the option to initialize the disk. Follow the prompts.
c. Reloadthe 5363 microcode ("324 Reloading the System Microcode Without Auto Configure" on
page 3-8).
d. Load SSP reference procedure ("322 Reloading the SSP Diskettes" on page 3-8).
e. Perform an IPL of the 5363 from disk using a select function 1, enter a code of 0000, and press the
Start Function key.
If the IPL is successful, run system test to verify that the problem is fixed ("328 Service Procedures
under SSP" on page 3-10).
If an SRC indicated that the disk drive is the failing FRU, install a new drive. The following FRUs
can cause IPL failures:
Disk drive
Disk adapter card (AIC2)
Disk cable assembly
Control storage processor card (AIG2)
Al board
Main storage processor cards (AIH2and AIJ2)
