Chapter 7 Troubleshooting Virtualization Engine Devices 71

For Internal Use Only

▼To Display Log Files and Retrieve SRNs

Use the /opt/svengine/sduc/sreadlog command to display log files and

retrieve the Service Request Numbers (SRN) for errors that need action. Data is

returned in the following format:

TimeStamp:nnn:Txxxxx.uuuuuuuu SRN=mmmmm

TimeStamp:nnn:Txxxxx.uuuuuuuu SRN=mmmmm

TimeStamp:nnn:Txxxxx.uuuuuuuu SRN=mmmmm

Example

Item Description

TimeStamp Timeand date when error occurred

nnn The name of the virtualization engine pair (v1 or v2)

Txxxxx The LUN wherethe error occurred.

Note: Txxxxx can representa physical or a logical LUN.

uuuuuuuu The unique ID of the drive or the virtualization engine router

SRN=mmmmm The SRN definedin numerical order

# /opt/svengine/sduc/sreadlog -d v1
