psrasc Command

Purpose

Collects centralized RAS data.

Syntax

psrasc type [ -d ] [ -n number ] -o outputFile logSpace/logStream

Description

The psrasc command extracts the Reliability/Availability/Serviceability (RAS) data log records centralized on a PowerHA® pureScale® log stream and builds a file in the RAS data AIX® format. The PowerHA pureScale service name is CentralizedLogService. Binding information for that service name must be setup before using the psrasc command.

RAS data types

When the specified type is syslog, the log records contain system log messages, including message initiator hostname. The format of the generated file is similar to the system log destination files. When the specified type is errlog, the log records contain error log entries. The generated file is an error log file that can be later exploited by the errpt command.

  2. To collect the 100 oldest log records of the log stream named CentralizedRAS/Syslog into the /var/adm/ras/cluster_syslog file on the PowerHA pureScale server

    identified by the CentralizedLogService service name and delete them, enter:

  3. To collect log records of the log stream named CentralizedRAS/Errlog into the file centralizedRAS_errlog on the PowerHA pureScale server identified by the CentralizedLogService service name, enter:
    psrasc errlog -o centralizedRAS_errlog CentralizedRAS/Errlog
  4. To collect and delete the 100 oldest log records of the log stream named CentralizedRAS/Errlog into the /var/adm/ras/cluster_errlog error log file on
