This article describes changing the target number assigned to an IQN when using the software iSCSI iniator.

1. From the VMware Infrastructure Client, remove the storage processor IP addresses from dynamic initators.
   
   
   1. Click on the ESX host.
   2. Click the Configuration tab.
   3. Click Storage Adapters.
   4. Select the software intiator adapter (vmhba32 for ESX 3.5 and vmhba40 for ESX 3.0).
   5. Click Properties.
   6. Click the Dynamic Discovery tab.
   7. Select each target from the array and remove it.
      
      
2. Log in to the ESX service console and change to the /var/lib/iscsi directory.
3. Edit the vmkbindings and vmkdiscovery files.
   
   Note: Make a backup of these two files by running cp vmkbindings vmkbindings.bak.
   
   Remove any unwanted entries and re-number the initiators of the entries you want to keep in both files.
   
   For example, changing the target number from 6 to 0.
   
   vmkbindings
   # Format:
   # bus target iSCSI
   # id id TargetName
   #
   0 6 iqn.1992-08.com.netapp:sn.84228148 0
   
   Change the 6 to 0.
   
   vmkbindings
   # Format:
   # bus target iSCSI
   # id id TargetName
   #
   0 0 iqn.1992-08.com.netapp:sn.84228148 0
   
   vmkdiscovery
   0 6 iqn.1992-08.com.netapp:sn.84228148
   
   Change the 6 to 0.
   
   vmkdiscovery
   0 0 iqn.1992-08.com.netapp:sn.84228148
   
   
4. Reboot the ESX host.
5. Log back into the ESX host using the VMware Infrastructure Client and re-add the storage processor IP addresses in Dynamic Discovery.
   
   
   1. Click on the ESX host.
   2. Click the Configuration tab.
   3. Click Storage Adapters.
   4. Select the software intiator adapter (vmhba32 for ESX 3.5 and vmhba40 for ESX 3.0).
   5. Click Properties.
   6. Click the Dynamic Discovery tab.
   7. Click Add.
   8. Enter the IP address and click OK.
      
      
6. Perform a rescan from the VMware Infrastructure Client.

The LUNs now appear with the desired target numbers.
