8 3-8 Viewing Multipathing Path States: – Active (I/O), Active, Disabled, and Dead Preferred path is designated with an * Active (I/O) is the current path being used under Fixed and MRU Topic 1: Storage Concepts 4

9 3-9 Enter the IP address/Port of each iSCSI target Maximum targets: 64 Static Discovery – Enter iSCSI Target Name Dynamic Discovery – Uses “Send Targets” to discover LUNs and all available paths Discovering iSCSI Targets Topic 2: iSCSI Storage (GUI & Command Line) 2

10 3-10 Configure Software Initiator: CHAP Authentication Topic 2: iSCSI Storage (GUI & Command Line) Challenge-Handshake Authentication Protocol (CHAP) is disabled by default To authenticate the ESX Server to the iSCSI Target, enable CHAP and enter CHAP name and CHAP secret CHAP can be set for each target individually 1

11 3-11 Viewing and Creating a VMFS Datastore Topic 4: VMFS Datastores (GUI & Command Line) 6

12 3-12 Add an Extent to your existing VMFS The list of possible extents to add will not include LUNs with an existing VMFS, or an RDM mounted to a VM Topic 4: VMFS Datastores (GUI & Command Line) 6

13 3-13 Expanding your SAN LUN You can expand a SAN LUN using Mfg. software ESX 3 cannot stretch the VMFS partition on the LUN – Same as adding an extent, results in multiple partitions combined – ESX 4 can perform dynamic expansion of VMFS volumes Topic 4: VMFS Datastores (GUI & Command Line) Process used here: 1.Use SAN software to add another 200 GB to an existing 500 GB LUN 2.Rescan from Storage Adapters shows 700 GB LUN Capacity 3.Properties of existing 500 GB VMFS LUN shows Capacity of 700 GB but Primary Partition of 500 GB 4.Choosing Add Extent allows adding the extra 200 GB extent 5.The final VMFS will be 700 GB with two extents, not one large primary partition 5
