Monitoring and Managing SAN Storage

Postby daniel » Mon May 11, 2015 1:09 pm

The esxcli storage san commands help administrators troubleshoot issues with I/O devices and fabric, and include Fibre Channel, FCoE, iSCSI and SAS protocol statistics. The commands allow you to retrieve device information and I/O statistics from those device. You can also issue Loop Initialization Primities LIP to FC/FCoE devices and you can reset SAS devices.
For FC and FCoE devices, you can retrieve FC events such as RSCN, LINKUP, LINKDOWN, Frame Drop and FCoE CVL. The commands log a warning in the vmKernel log if it encounters too many Link Toggling or frame drops
To retrieve and reset the IO Device Management module

1 Retrieve all events for a Fibre Channel I/O device.

Code: Select all

esxcli storage san fc events get


2 Clear all I/O Device Management events for the specified adapter.

Code: Select all
