Примечания к выпуску для Cisco Cisco MDS 9000 SAN-OS Software Release 1.0

There are no new features in this release.

This sections lists limitations or restrictions associated with this release.

If you execute a SANTap command that is equal to or greater than 18 characters, the command fails and 
displays an error message like the following:

switch# sh santap module 8 dvt

remuser too long

Commands that have fewer characters, such as the sh ivr command or the sh zoneset act command, 
execute correctly. 

You might see this issue if you are collecting information from the supervisor module and you attempt 
to execute SANTap commands that are 18 characters in length or more.

There are two ways to work around this issue:

Attach to the module and collect the information on the module itself.

Enter a command with less than 18 characters.

The Cisco MDS SSI Release 4.2(3i) image for SANTap is not compatible with the Hardware 
Acceleration vStorage APIs for Array Integration (VAAI) feature of vSphere 4.1. The result of using 
SANTap and vSphere 4.1 with the Storage Hardware Acceleration feature enabled will be a failure of 
the SANTap module—either the Cisco MDS 9000 Series SSM, the Cisco MDS 9000 MSM-18/4, or 
Cisco MDS 9222i module. 

 lists the SCSI commands that are issued as part of vSphere 4.1 Hardware Acceleration.
