This issue occurs because ESXi 5.0 attempts to connect to all configured or known targets from all configured software iSCSI portals. If a connection fails, ESXi 5.0 retries the connection 9 times. This can lead to a lengthy iSCSI discovery process, which increases the amount of time it takes to boot an ESXi 5.0 host.
VMware is delivering an ISO file for this patch release due to the nature of this issue. This is not common practice and is only done in special circumstances.
Note: The ISO containing ESXi 5.0 Patch 01 is only available to licensed customers, and is not available for download without an entitlement. However, non-licensed customers can download Patch 01 to upgrade an existing version of ESXi 5.0 to resolve this issue.
To list the current number and configuration of an ESXi host's network portals, run this command:
esxcli iscsi networkportal list
