Header & Data Digests 

 

Digests  are  an  advanced  form  of  error-detection  specified  by  iSCSI.  These  may  be  used  for 
error detection on the iSCSI Headers and or the Data portion of the packet. Depending on the 
hardware  used, enabling  Digests  may  affect  the  performance  so  it  is  recommended  that  this 
option be only enabled when you suspect you are receiving corrupted IP packets.  

There are three encoding options for each of the Digests.  

• 

Selecting None forces Data Digests to off  

• 

Selecting CRC32 forces on Data Digests to use the CRC32 encoding.  

• 

Selecting the None/CRC32 option allows the initiator to select the whether 

Data Digests are enabled  

Current Connections 

 

This  section  lists  the  current  connections  i.e.  logged  on,  from  iSCSI  hosts.  It  displays  which 
initiator is connected to which Target device.  

Note it is possible that more than one host to be connected to any target device or one host to 
multiple target devices.  

It  is  possible  to  send  a  logout  request  to  a  host  by  highlighting  the  host  connection  and 
pressing the logout button  

Note:  many  initiators  are  configured  to  automatically  reconnect  after  completing  the  logout 
request. If this is the case then the connections window may not show any change.  

3.11 SCSI Bus 

 

This configuration  page  will allow the administrator to configure  a number of parameters that 
control the behaviour of the SCSI bus.  

From within the main menu select the SCSI Initiator icon from the SCSI System section.  

The GUI will now display the following window
