2 Adapter Management
On VMware ESX/ESXi you can identify and
manage ATTO adapters using the VMware
vSphere Client, or the Service Console. On ESXi,
the Service Console is referred to as Local Tech
Support Mode.
2.1 vSphere Client
With VMware vSphere Client, you can identify
ATTO adapters on a VMware ESX/ESXi system,
and view the attached storage devices.
1 Start vSphere Client from your local workstation
and select the host containing one or more
ATTO adapters.
2 Click the Configuration tab, and then select
Storage Adapters under Hardware in the left
pane.
3 A list of all storage adapters in the system is
displayed. The Model, Identifier (WWN or SAS
address) and Targets are shown for each
adapter channel.
TBD - Insert a screenshot from vSphere client
showing ATTO adapter
2.2 Service Console
Using the Service Console, information about each
adapter channel can be found in the /proc/scsi
filesystem, under /proc/scsi/<driver name>.
To view details on a specific adapter channel, run
the following command:
# cat /proc/scsi/<driver name>/<channel>
This command displays the following information:
“Adapter type
“Driver, BIOS and Firmware versions
“Driver Parameters
“Adapter Model and Identifier (WWN or SAS
address)
“Virtual Port Information
“Discovered Targets
“Driver Statistics
A sample output is shown below:
~ # cat /proc/scsi/celerity8fc/6
ATTO Celerity 8GB Fibre Channel Adapter
Driver version 1.31
BIOS version 07/28/2010
Firmware version 06.01.00
