HP EVA Array iSCSI Connectivity Option - Manual (Page 177)

• Verify that the iSCSI Target status is connected with the command iscsi-ls –l.
• For a Macintosh Initiator:
• Verify that the iSCSI driver is installed.
• Ping the mpx100/100b iSCSI port from the iSCSI Initiator.
• Verify that the target's Visible field is set to Yes in the Manager Targets screen.
• Verify that the target's status in the Target Status field is connected.
• For an OpenVMS Initiator:
• Verify that TCP/IP has been started and is properly configured.
• Verify that the initiator has been loaded and that the device DEA0 exists.
• Ping the mpx100/100b iSCSI ports from the OpenVMS host.
• Make sure the iSCSI ports and iSNS server (if applicable) have been defined in the TCP/IP
host database.
• On the mpx100/100b:
• Verify that the mpx100/100b iSCSI port’s IP address and subnet mask are set properly.
• Verify that the mpx100/100b iSCSI port is in the same LAN as the iSCSI Initiator.
• Check the iSCSI port CHAP settings (if any).
iSCSI Initiator, EVA iSCSI target, and EVA LUN connections
If the iSCSI Initiator connects to the EVA iSCSI target but does not see any EVA LUNs, check the following:
• Check in HP Command View EVA to verify that a LUN iSCSI is presented to the iSCSI Initiator.
• Using mpx Manager or the CLI, verify that the mpx100/100b has the LUN assigned to the initiator.
• Check the iSCSI Initiator’s iqn name syntax.
If the iqn name has changed, choose from one of the following options to reinstate the original
iqn
name:
• For Windows—In the initiator GUI, click the General tab, and then select Change > Reset to
reset it to the original iqn name.
• For Linux—Edit the InitiatorName setting in the /etc/initiatorname.iscsi file.
• For Linux and Windows—Reinstall the initiator to create a valid iqn name.
• For OpenVMS—Ensure that the TCP/IP host name has not changed. If it has changed, it
needs to be changed back and the initiator needs to be restarted, or the LUNs need to be
re-presented using the new iqn name.
• Rescan the disks:
• For Windows, select Disk Management.
• For Linux, issue the /etc/rc.d/init.d/iscsi restart command.
• For OpenVMS, issue the mcr sysman io autoconfigure /log command.
• Reboot the iSCSI Initiator.
HP Command View EVA refresh
The HP Command View EVA user interface periodically performs an automatic refresh to ensure that the
user interface accurately reflects the state of the array. However, the automatic refresh may interfere with
your work when you are completing the fields on the iSCSI controller properties window. Specifically,
while you are entering information, an automatic refresh may occur and reset the fields, causing you to
lose the data you have entered.
To ensure that you retain iSCSI controller property field information in HP Command View EVA, do
one of the following:
• Enter a portion of the data between page refreshes, and then click Save to store the information.
Enter the rest of the data and then click Save.
• Change the refresh interval for the entire GUI to a larger value in Agent Options > User Interface.
The default value for the content pane is 60 seconds.
