Save Input Output RAID Controller Module (IOC) Dump

This command saves the IOC dumps from the RAID controller modules in a storage array to a file on a host.

Syntax

save IOCLog [file="filename"]

Parameter
Parameter Description

file

The file path and the file name to which you save the IOC dump. Enclose the file name in double quotation marks (" "). For example:

file="C:\Array Backups\IOCcoredump1.7z"

This command saves the data to a compressed file and adds the file extension .7z to the saved file. The default name of the file that contains the IOC-related data for RAID controller modules in the storage array uses the WWN of the storage array.

  • NOTE: This command retrieves from both RAID controller modules the IOC dump log data and the IOC dump metadata. Using a 7zip file format, the retrieved data is archived and compressed into a single file with a file name of your choice. The 7zip archive file contains the following:

    filename+”IOCLog”+[A|B].gz – the IOC logs retrieved from RAID controller module 0 or RAID controller module 1 if available

    filename+”IOCLogInfo”+[A|B].txt – the IOC logs metadata info retrieved from RAID controller module 0 or RAID controller module 1. If the IOC log data cannot be retrieved from a RAID controller module, the IOC log data cannot be retrieved from a RAID controller module, the metadata .txt file will contain the error condition and reason.

    Following are the error conditions:

    The RAID controller module platform and HIC do not support IOC dump.

    The RAID controller modules have not collected IOC dump data.

    The compressed logs are not in a human-readable format. You must return the logs to Technical Support to be evaluated.
