Then, I tried to install driver bundle from here: http://www.vmware.com/support/vsphere4/doc/drivercd/esx40-scsi-bfa_400.1.1.1-1.0.4.html

Installation failed:

C:\Program Files\VMware\VMware vSphere CLI\bin>vihostupdate.pl --server 192.168.
70.16 --install --bundle C:\bfa.zip
Enter username: root

quire this host to be in maintenance mode: cross_vmware-esx-drivers-scsi-bfa_400
.1.1.1.1-1.0.4.00000. Please put the host in maintenance mode to proceed.

Then, I have entered host in maintenance mode amd other error appeared:

C:\Program Files\VMware\VMware vSphere CLI\bin>vihostupdate.pl --server 192.168.
70.16 --install --bundle C:\bfa.zip

• only 1 MB available).*

How I can install these drivers?

I discovered that I have no space on default Scratch Config location.

Then I go to Configuration -> Advanced Settings -> ScratchConfig and look at ScratchConfig.ConfiguredScratchLocation and set it to Datastore (/vmfs/volumes/ID_of_datastore)

Reboot required to change takes effect.

Then I issued a command:

vihostupdate.pl --server 192.168.70.16 --install --bundle C:\bfa.zip and adapters appears in configuration tab!!!!
