If a hardware error, etc. occurs during backup, the following symptoms may be displayed:
swstbackstat (Backup execution status display command) displays "failed" or "?????" in the Status column.
swstsyncstat (Backup synchronous processing progress display command) displays "failed" or "?????" in the Status column.
swstreststat (Restore execution status display command) displays "failed" or "?????" in the Status column.
swsthistdisp (History information display command) displays "failed" or "?????" in the Status column.
swstexecstat (Execution status display command) displays "sync(failed)", "snapshop(failed)", "restore(failed)", or "?????" in the Status column.
swsttrkstat (Tracking status display command) displays "failed" or "?????" in the Status column.
The message swst0603, swst0634, swst0719, or swst0740 is displayed during command execution.
If the execution status display command and history information display command display "failed" in the Status column, a hardware error has occurred during physical copying, and the copy processing has failed.
If the message swst0603, swst0634, swst0719, or swst0740 is displayed during command execution and the same error occurs even if the command is re-executed, a hardware error, etc. has occurred, causing Advanced Copy to fail.
If any of these messages, statuses or symptoms is generated, a hardware error may have occurred in the transaction volume or backup volume. Check the hardware status, and if a hardware error is found, fix the cause of the error, then re-execute the processing.
