A software FCoE adapter is a software code that performs some of the FCoE processing. The adapter
can be used with a number of NICs that support partial FCoE ooad. Unlike the hardware FCoE
adapter, the software adapter must be activated.
Scanning Storage Adapters
You must perform a rescan operation each time you recongure your storage setup.
You can scan by using the vSphere Web Client, the vicfg-rescan vCLI command, or the esxcli storage
core adapter rescan command.
n
esxcli storage core adapter rescan supports the following additional options.
n
-a|--all or -A|--adapter=<string> – Scan all adapters or a specied adapter.
n
-S|--skip-claim – Skip claiming of new devices by the appropriate multipath plug-in.
n
-F|--skip-fs-scan – Skip lesystem scan.
n
-t|--type – Specify the type of scan to perform. The command either scans for all changes (all) or
for added, deleted, or updated adapters (add, delete, update).
n
vicfg-rescan supports only a simple rescan operation on a specied adapter.
Rescanning a storage adapter with ESXCLI
The following command scans a specic adapter and skips the lesystem scan that is performed by default.
esxcli <conn_options> storage core adapter rescan --adapter=vmhba33 --skip-claim
The command returns an indication of success or failure, but no detailed information.
Rescanning a storage adapter with vicfg-rescan
Run vicfg-rescan, specifying the adapter name.
vicfg-rescan <conn_options> vmhba1
The command returns an indication of success or failure, but no detailed information.
Retrieving SMART Information
You can use ESXCLI to retrieve information related to SMART. SMART is a monitoring system for computer
hard disks that reports information about the disks.
You can use the following example syntax to retrieve SMART information.
esxcli storage core device smart get -d device
What the command returns depends on the level of SMART information that the device supports. If no
information is available for a parameter, the output displays N/A, as in the following sample output.
