Presenting an EVA LUN to an iSCSI Initiator is a two-step process in HP Command View:
1. Presenting the LUN to the iSCSI host entry. This communication presents the LUN from the
EVA FC ports to the mpx100/100b FC ports.
2. Presenting the LUN to the iSCSI Initiator. This communication presents the LUN from the
mpx100/100b Gigabit Ethernet ports to the iSCSI Initiator.
Troubleshoo
ting EVA communication with the mpx100/100b
If there is a p
roblem with HP Command View EVA com municating with the mpx100/100b or not
discoverin
gLUNs,verifythat:
• The mpx100/100b is powered on.
• The mpx100/100b management port is cabled to the IP net work.
• The mpx100/
100b management por t IP address, subnet mask, and gateway are set properly.
• The HP Command View application ser ver NIC IP address, subnet mask, and gateway are
set properly.
• The mpx100
/100b management port is on the same IP network as the HP Command View
EVA application server.
• The iSCSI controller’s management port connection status is online in HP Command View EVA.
Troubleshooting EVA or LUN FC port connections
If the mpx100/100b does not see EVA ports or LUNs connected to the FC ports:
• Verify that the mpx100/100b is p owered on.
• Verify that the Fibre Channel link light is green.
• If your configuration is fabric connect mode, check to see if the mpx100/100b FC ports are
zoned with the EVA FC ports.
• If your configuration is direct connect mo d e, check to see if EVA ports connected to the
mpx100/100b FC ports are set to direct connect.
• Verify that the EVA p orts and LUNs are discovered and online to the mpx100/100b are using the
mpx Manager GUI or CLI.
• In HP Command View EVA , verify that the Vdisk is uses FC ports to present the Vdisk to the
iSCSI host entry.
Troubleshooting iSCSI Initiator conne ctions to the EVA iSCSI targets
If the iSCSI Initiator cannot connect to the EVA iSCSI targets presented by the mpx100/100 b :
• For a W
indows Initiator:
• Verify that the iSCSI driver is installed.
• Ping the mpx100/100b iSCSI port from the iSCSI Initiator.
•Sele
ct General > Secret and check the security setting on the initiator.
• Verify that the iSCSI Initiator’s iqn name changed in the General tab.
• Verify that the iSCSI Port IP address is added to Target Portals on the Discovery tab.
•Ver
ify that the iSCSI Target status is connected on the Targets tab.
• For a Linux Initiator:
• Verify that the iSCSI driver is installed.
•Pin
g the mpx100/100b iSCSI Port from the iSCSI Initiator.
• Check for security settings, if any, in authentication settings in the /etc/iscsi.conf file.
• Verify that the iSCSI IP port address is added to the Discovery Address setting in
/etc/iscsi.conf file.
•Ve
rify that the iSCSI Target nam e is added to the TargetName setting in the
/
etc/iscsi.conf file.
