General troubleshooting procedure

Edit online

This procedure is valid for all IBM® Storage Protect Snapshot applications.

The starting point for problem determination is the summary log file located in the <ACS_DIR>/logs directory. The summary log file name is summary.<timestamp>.log where <timestamp> is an entry that represents the four-digit year, month, and day (for example, summary.20090817.log). A new log file is created each day. This file contains a list of all operations and the most important messages. Each line begins with one of these prefixes to indicate the type of operation:
Table 1. Message prefixes used in the summary log file
Prefix Operation
GEN Generic message
DB Database backup or restore; inquire or delete of FlashCopy® backups
MON Monitoring of the background copy that is performed by the storage device
TSM Off-loaded backup to IBM Storage Protect
MNT Mount and unmount services
CLO FlashCopy cloning operations
The summary log file only contains the information about operations that were performed and whether they completed successfully. Error messages are also logged when they occur. A dedicated log file is created for each operation in the <ACS_DIR>/logs/details. These files should be checked for detailed information when an error occurs.

This summary log file example shows a FlashCopy backup of a database. Messages with the DB prefix are issued by the database client. This is the application that requests the backup operation.
