4–60 Troubleshooting
18. Perform the initial write pass.
19. Allow DILX to compare the read and write data.
20. Accept the default percentage of reads and writes that DILX compares.
21. Enter the unit number of the disk drive you want to test. For example, if you want
to test D107, enter the number 107.
22. If you want to test more than one disk drive, enter the appropriate unit numbers
when prompted, otherwise, enter “n” to start the test. Use the command
sequences shown in Table 4–14 to control the write test.
DILX Error Codes
Table 4–16 explains the error codes that DILX may display during and after testing.
Configuration Utility
Use the configuration (CONFIG) utility to add one or more storage devices to the
subsystem. This utility checks the device ports for new disk drives then adds them to
the controller’s configuration and automatically names them. See HSZ80 Array
Controller ACS Version 8.3 Configuration and CLI Reference Guide, for more
information about using the CONFIG utility.
Table 4–16 DILX Error Codes
Error Code Explanation
1 Illegal Data Pattern Number found in data pattern header. DILX read data
from the disk and discovered that the data did not conform to the
pattern in which it was previously written.
2 No write buffers correspond to data pattern. DILX read a legal data
pattern from the disk, but because no write buffers correspond to the
pattern, the data must be considered corrupt.
3 Read data does not match write buffer. DILX compared the read and
write data and discovered that they didn’t correspond.
