    1 Installing and configuring VMware for the XP disk array You and the HP service representative each play a role in installation. The HP service representative is responsible for installing the disk array and formatting the disk devices. You are responsible for configuring the host server for the new devices with assistance from the HP service representative.

  • Page 8: Fibre Channel Interface

    Fibre Channel interface The XP family of disk arrays and the SVS 200 support these Fibre Channel elements: Connection speeds of 1 Gbps, 2 Gbps, and 4 Gbps Short-wave non-OFC (open fiber control) optical interface Multimode optical cables with SC or LC connectors Public or private arbitrated loop (FC-AL) or direct fabric attach Fibre Channel switches Even though the interface is Fibre Channel, this guide uses the term “SCSI disk”...

  • Page 9: Snmp Configuration

    SNMP configuration The XP family of disk arrays and the SVS 200 support standard Simple Network Management Protocol (SNMP) for remotely managing arrays. The SNMP agent on the service processor (SVP) performs error-reporting operations requested by the SNMP manager. SNMP properties are usually set from the SVP but they can also be set remotely using XP Remote Web Console or XP Command View Advanced Edition Software.

    IMPORTANT: HP recommends selecting host group mode 19 (processing time for reserve commands during I/O processing is shortened). Your HP representative will select host group mode 19 for you. CAUTION: Changing host group modes for ports where servers are already installed and configured is disruptive and requires the server to be rebooted.

    Fabric and connection parameter settings Set each array port to FABRIC ON or OFF with connections of POINT-TO-POINT or FC-AL as shown in the following table and figures. For detailed topology information, refer to the HP StorageWorks SAN Design Reference Guide at: http://www.hp.com/go/sandesign.

    Clustering is the organization of multiple servers into groups. Within a cluster, each server is a node. Multiple clusters compose a multi-cluster environment. The following example shows a multi-cluster environment with three clusters, each containing two nodes. The nodes share access to the disk array. Figure 4 Multi-cluster environment Within the Storage Area Network (SAN), the clusters may be homogeneous (all the same operating system) or they may be heterogeneous (mixed operating systems).

    VMware ESX Server 3.0x Open Virtual Infrastructure client and select the configuration tab, then select Advanced Settings. In the left pane of the “Advanced Settings” window, select Disk, then scroll down to “Disk.MaxLUN”. Verify that the value is large enough to support your configuration (default=8). If the value is less than the number of LUNs you have presented then you will not see all of your LUNs.
