Configuring the PowerVault 35F: Dell PowerVault 35F User's Guidefile:///C|/Users/rishi_sood/Desktop/35F/ug/config_2.htm[3/21/2013 11:16:19 AM]Host Device ConfigurationThe host system using a Fibre Channel Host Bus Adapter (HBA) will typically map Fibre Channel devices into theexisting device mapping scheme used by that operating system. This usually results in the Fibre Channel HBAmapping Fibre Channel AL_PA’s to SCSI target addresses. The HBA will claim enough SCSI bus entries to allow for125 Fibre Channel targets to map to SCSI Bus:Target entries. This is usually done by a fixed mapping of AL_PA toBus:Target. In such a configuration, the PowerVault 35F corresponds to a Bus:Target identifier, with the SCSI devicesattached to the PowerVault 35F appearing as logical units (LUNs). In addition, some operating systems can extend theavailable SCSI limit of 15 per bus.Although this is not an issue for the operating system or most applications, there are cases where older applicationscan have expectations about what are valid SCSI ID’s, and not deal correctly with certain mappings. In particular,applications have been seen to have difficulties addressing target ID’s greater than 15 (e.g. 16 and up). This problemcan be resolved by configuring the PowerVault 35F to use hard addressing, and setting the AL_PA used by the unit toa value that the HBA will map to an ID with a value less than 16.For example, depending on the Fibre Channel HBA, if the hard AL_PA selection is 1, the address is 1. If the selectionis 125, the AL_PA address is 0xEF. Some Fibre Channel HBA’s will configure differently, so verify the AL_PA bytoggling to hard addressing and selecting an address.Device ManagementThe PowerVault 35F can be managed through the RS-232 port, over Ethernet via Telnet or a web browser, or viaSNMP. FTP and TFTP are also supported for firmware downloads.SerialThe serial port allows for configuration of all device characteristics.EthernetThe 10BaseT Ethernet port must first be configured via the serial port with an appropriate IP address and subnet maskprior to use unless the default values are to be used. Default values are IP address 1.1.1.1, and a subnet mask of255.255.255.0.NOTE: The PowerVault 35F only supports a 10BaseT Ethernet network connector. 100BaseT Ethernet is notcurrently supported.SNMPThe PowerVault 35F includes SNMP management support. SNMP is transported via the Ethernet connection (10BaseTport). SNMP support allows configuration and management using any standard SNMP management tool. SNMP datais defined in the SNMP MIB. Dell provides a private MIB for configuration of the PowerVault 35F. The Dell privateMIB includes all objects configurable from the terminal user interface. The Dell private MIB also includes some FibreChannel and SCSI statistics which are not accessible via the serial interface. SNMP support also includes Traps, which
