Goal

This document explains how to configure Oracle Explorer Data Collector and give some hints for its use.

For array troubleshooting, it is important to collect data from a failed array out-of-band, that is, over the network rather than via the data path. Use this to prevent getting some SCSI errors, slowing down the I/O activity, or at worst hanging the system which has a failed array. Also, this way would collect the array's configuration when only the access paths are failed.

For information about Oracle Explorer Data Collector and how to download it, please refer to <Document 1312847.1> Sun Explorer Product Information Center.

Solution

Until now, Oracle Explorer Data Collector collect the se3kxtr of all the connected arrays in in-band status. Now it is possible to collect the se3xtr in out-of-band status with the Oracle Explorer Data Collector release 5.3 and above. This new feature works like the T3 extractor, ie. a file creation with the name or IP address of the arrays and their possible password.

Configuration:

• Add the arrays in the file /etc/opt/SUNWexplo/se3kinput.txt, like this:
  
  
  # Input file for extended data collection
  # Format is HOST PASSWORD
  # Explorer requires that the mode of se3kinput.txt is 0400 or 0600
  ---IP hidden--- explorer

• Do the following checks:
  • Check that the array name exist in the /etc/host file, or in the database for the used name resolution protocol.
  • Check that each registered array can reached using ping.
  • Check for each array, that it's password matches the one registered in the se3kinput.txt.

Using Oracle Explorer Data Collector:

• Without any option, Oracle Explorer Data Collector collects all the se3kxtr information in in-band status.
• With -w se3kextended option Oracle Explorer Data Collector will collect se3kxtr information for each array registered in the se3kinput.txt file.

Example of output when using Oracle Explorer Data Collector with the -w se3kextended option:

This interactive module allows you to obtain data for SE3xxx arrays which
are network accessible from this host.

You will be prompted for an array name and password.  If arrayname cannot
be resolved, please use the IP address.  If the array has no password, press
return when prompted for one.

To end the prompting, type return, at which point, data collection will begin.

Please enter the name of the SE3xxx array: ---IP hidden---
Feb 22 17:00:10 s4u-280ra-epar02[3625] se3kextended: Verifying connection to ---IP hidden--- using sccli.
Please enter the password for ---IP hidden---, if any:
Feb 22 17:00:17 s4u-280ra-epar02[3625] se3kextended:
Please enter the next SE3xxx array name or press return to continue.

Please enter the name of the SE3xxx array: 

Feb 22 17:00:25 s4u-280ra-epar02[3625] se3kextended: Gathering data for ---IP hidden---.
Gathering data for ---IP hidden---.

For regular Oracle Explorer Data Collector launching, modify the crontab Oracle Explorer Data Collector commands to contain the -w se3kextended option.

Prevent all in-band access by configuring with telnet or serial port:
