SANtricity 11.8 Commands ( CA08871-194 ~ 196 )

Start input output controller (IOC) dump

The start IOCLog command produces a dump of the IOC log of data transmissions between a host and a controller.

Supported Series

This command applies to any individual storage system, including the HB2100/HB2200/HB2300, HB5100/HB5200, AB6100 and AB3100 series, as long as all SMcli packages are installed.

Roles

To execute this command on an HB2100/HB2200/HB2300, HB5100/HB5200, AB6100, or AB3100 storage system, you must have the Storage Admin role.

Context

Controllers are identified as "a " or "b". Each controller can have up to four host channels; each channel is uniquely identified by a number from 1 through 4.

Syntax

start IOCLog [(a1 | a2 | a3 | a4 | b1 | b2 | b3 | b4)]
[overwrite=(TRUE | FALSE)]

Parameters

Parameter Description

controller-channel identifiers

This parameter specifies the controller and host channel from which to produce the IOC dump. Valid controller identifiers are a or b, where a is the controller in slot A, and b is the controller in slot B. Host channels have numerical identifiers. Enclose the controller identifier and host channel identifier in square brackets ([ ]).

Valid controller identifier and host channel values are a1, a2, a3, a4, b1, b2, b3, b4.

If you do not specify a controller, the storage management software returns a syntax error.

overwrite

This parameter causes the new IOC log dump to overwrite an existing dump. To overwrite the existing dump, set this parameter to TRUE. The default value is FALSE.

Notes

This command generates a debug log from the IOC of the selected controller and stores the data in a compressed format in a persistent memory buffer on the controller. You can retrieve the data from the debug log using the save IOCLog command. The controller returns an error for these conditions:

  • The controller platform and HIC do not support an IOC dump.

  • The specified controller has an outstanding IOC dump and the overwrite parameter is false.

  • The specified controller identifier or channel identifier are out of the valid range.
