Data Inconsistencies and STO_DATA Tests
The STO-DATA maintenance object is not a hardware component, but a strategy
used to test for consistency between corresponding files on the different storage
devices. When inconsistencies are found, STO-DATA errors and alarms are
generated. The translation, announcement, and software update files are
checked by comparing timestamps created when the files were saved from
system memory. The boot image files are checked by comparing vintage
numbers. The other files are not checked.
On systems with simplex SPE, a STO-DATA test compares the files on tape to
those on the disk. On systems with duplicated SPEs, the following comparisons
of corresponding files are made:
1. Disk to tape (active SPE)
2. Disk to tape (standby SPE)
3. Disk (active SPE) to disk (standby SPE)
4. Tape (active SPE) to tape (standby SPE)
The data consistency tests are run as part of the short and long demand test
sequences and automatically during daily scheduled maintenance. Test results
point to which files, if any, are out of date.
In addition to the data consistency tests, checksum tests are run during the long
demand test sequence to verify that the checksums of both copies of the boot
image on each storage device are the same. This capability is useful when the
system has booted using a boot image other than the first copy on disk. (An
alarm and unique error code identify this situation). In addition to test results, you
can use the
list configuration software
command to retrieve detailed
information about the files on each storage device.
