The list dumps commands return a list of dumps in the appropriate directory.
An audit log keeps track of action commands that are issued through an SSH session or from the SAN Volume Controller Console. To list the audit log files in the /dumps/audit directory on the current configuration node or on the designated node, issue the svcinfo lsauditlogdumps command. To list a specified number of the most recently audited commands, issue the svctask catauditlog command. To dump the contents of the audit log to a file on the current configuration node, issue the svctask dumpauditlog command. This command also clears the contents of the audit log.
Dumps contained in the /dumps/cimom directory are created by the CIMOM (Common Information Model Object Manager) that runs on the SAN Volume Controller cluster. These files are produced during normal operations of the CIMOM. To list all the files in the /dumps/cimom directory, issue the svcinfo lscimomdumps command.
Dumps that are contained in the /dumps/elogs directory are dumps of the contents of the error and event log at the time that the dump was taken. An error or event log dump is created by using the svctask dumperrlog command. This dumps the contents of the error or event log to the /dumps/elogs directory. If no file name prefix is supplied, the default errlog_ is used. The full default file name is errlog_NNNNNN_YYMMDD_HHMMSS, where NNNNNN is the node front panel name. If the command is used with the -prefix parameter, the prefix value is used instead of errlog. To list all dumps in the /dumps/elogs directory, issue the svcinfo lserrlogdumps command.
Dumps contained in the /dumps/feature directory are dumps of the featurization log. A featurization log dump is created by using the svctask dumpinternallog command. This dumps the contents of the featurization log to the /dumps/feature directory to a file called feature.txt. Only one of these files exists, so every time the svctask dumpinternallog command is run, this file is overwritten. To list all dumps in the /dumps/feature directory, issue the svcinfo lsfeaturedumps command.
Dumps that are contained in the /dumps/iostats directory are dumps of the per-node I/O statistics for disks on the cluster. An I/O statistics dump is created by using the svctask startstats command. As part of this command, you can specify a time interval for the statistics to be written to the file; the default is 15 minutes. Every time the time interval is encountered, the I/O statistics that have been collected are written to a file in the /dumps/iostats directory. The file names that are used for storing I/O statistics dumps are Nm_stats_NNNNNN_YYMMDD_HHMMSS, Nv_stats_NNNNNN_YYMMDD_HHMMSS, and Nn_stats_NNNNNN_YYMMDD_HHMMSS, where NNNNNN is the node front panel name for the MDisk, VDisk, or node. To list all dumps in the /dumps/iostats directory, issue the svcinfo lsiostatsdumps command.
Dumps that are contained in the /dumps/iotrace directory are dumps of I/O trace data. The type of data that is traced depends on the options specified by the svctask settrace command. The collection of the I/O trace data is started by using the svctask starttrace command. The I/O trace data collection is stopped when the svctask stoptrace command is used. It is when the trace is stopped that the data is written to the file. The file name is prefix_NNNNNN_YYMMDD_HHMMSS, where prefix is the value entered for the -filename parameter in the svctask settrace command, and NNNNNN is the node front panel name. To list all dumps in the /dumps/iotrace directory, issue the svcinfo lsiotracedumps command.
Dumps that are contained in the /dumps/mdisk directory are copies of solid-state drive (SSD) MDisk internal logs. These dumps are created using the svctask triggermdiskdump command. The file name is mdiskdump_NNNNNN_MMMM_YYMMDD_HHMMSS, where NNNNNN is the front panel name of the node that contains the MDisk, and MMMM is the decimal ID of the MDisk. To list all dumps in the /dumps/mdisk directory, issue the svcinfo lsmdiskdumps command.
Dumps that are contained in the /dumps directory result from application abends. Such dumps are written to the /dumps directory. The default file names are dump.NNNNNN.YYMMDD.HHMMSS, where NNNNNN is the node front panel name. In addition to the dump file, there might be some trace files written to this directory, are named NNNNNN.trc.
To list all dumps in the /dumps directory, issue the svcinfo ls2145dumps command.
The final option available in the list dumps command series is the svcinfo lssoftwaredumps command. This command lists the contents of the /home/admin/upgrade directory; files are copied to this directory during software upgrades.
All of the list dumps commands can accept a node identifier as input. If this identifier is not specified, the list of files on the current configuration node are displayed. If the node identifier is specified, the list of files on that node are displayed.
Because files can only be copied from the current configuration node (using secure copy), you can issue the svctask cpdumps command to copy the files from a nonconfiguration node to the current configuration node.
