    <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Since it's only testing I simply plugged a crossover cable between the dedicated iSCSI interfaces (GBit)&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hi,&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I've successfully installed and configured IET - no problem so far.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Then I've created a test lun and configured ESX to use it - again no problem.&lt;/P&gt;&lt;P&gt;After some successful testing I removed the iSCSI LUN from ESX , deleted it on IET, created a new one and configured ESX to use it.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Now ESX tries to access the old (deleted) LUN and the vmkernel log gets filled with the following message:&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;messages.1:Jan 31 17:56:14 XXX iscsid\[16990]: iSCSI poll session ioctl failed for iqn.2007-01.xxx.xxx:iscsi.disk1, rc 0&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Is there a way to "convince" ESX not to search / access the old deleted LUN?&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;ESX does hold on to iSCSI LUNs in one of its configuration databases. Try renaming the iSCSI LUN iqn and alias in the ietd.conf file so that ESX things its completely different.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Chances are ESX just got confused if the iqn and alias of the previous IET LUN is the same as the old one.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Paul&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Dumb question, but what kind of network switch are you using?  Try powering the switch off and on again... doubtful, but I've seen switches mess up MAC tables this way.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Paul&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;I've had to go through several steps to rid a running ESX 3.x host of swISCSI.  Sometimes even all of these steps do not work because the host is rendered unstable and the iscsi module panics, won't unload, etc.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;1.  In the VIC, Storage Adapters, Properties, General, Configure, Uncheck "Enabled"&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;2.  esxcfg-swiscsi -d&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;3.  esxcfg-swiscsi -k&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;4.  delete applicable iscsi target entries from:&lt;/P&gt;&lt;P&gt;/var/lib/iscsi/vmkbindings&lt;/P&gt;&lt;P&gt;/var/lib/iscsi/vmkdiscovery&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;5.  esxcfg-swiscsi -e&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;6.  esxcfg-swiscsi -s&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;7.  Repeat step 1&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;8.  In VIC, Run a rescan of vmhba40 to get rid of the old iscsi symbolic link in /vmfs/volumes/&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
