This section describes connecting an EMC Symmetrix to a NUMA-Q 1000 MQuad running Windows NT through a Fibre Channel Arbitrated Loop. Troubleshooting information is also included.
ATTENTION All configuration settings on the EMC Symmetrix must be carried out by EMC personnel.
For Windows NT, the EMC director flags must be set differently than with DYNIX/ptx. The following director flags must be set to on for the FC ports connecting to an MQuad running Windows NT: T, C, A, UWN, H, Loop ID. The D bit is only needed when clustering is being used.
These are the steps to install a V4 FC host adapter (Emulex SuperFly 7000e) with miniport drive in an MQuad:
Power down the desired MQuad.
Install the FC host adapter in an open slot.
Boot Windows NT.
Open the SCSI Adapters window from the Control Panel.
Open the Drivers tab, click on Add, then click on Have Disk.
Enter the path to the driver for the SuperFly 7000e (Oemsetup.inf). The most current driver is 4.20SLI-2 and can be downloaded from the following FTP site:
ftp://ftp.emulex.com/pub/fibre/lp7xxx/lp7driver/nt/scsi/4.20SLI-2
Reboot the MQuad.
If the Symmetrix has drives configured to its FC ports (the ports that are connected to the MQuad), and the FC optical cable is connected, the MQuad should start seeing drives on the Symmetrix after reboot.
Normally, if you configure two FC host adapters to connect to the same set of Symmetrix drives (that is, if you set up redundant connections), Windows NT views the drives as two independent sets. You can remedy this condition by running a utility from EMC called PowerPath. This software tells Windows NT that the two boards are a dual-connection to the same disks. Currently there has been only minor testing with this utility.
If Windows NT does not see any drives on the Symmetrix, check the back of the FC host adapter board. The green light should be on and steady and the yellow light should be flashing. If the yellow light is not flashing, or if the green light is blinking, check the following conditions:
Ensure that the TX and RX ends of the optical cable are installed on the correct ports. (It is easy to accidentally swap TX and RX.)
Check that the optical connectors are seated solidly on the ports.
If the connections are correct and solid, remove the connectors from the ports and check whether the connectors or ports need cleaning. You can used canned air to blow out the ports.
DANGER Do not point an optical connector toward your eye. Eye damage can occur from laser light.
Ensure you are receiving an optical signal. You can do this with a line tester or by simply holding a piece of white paper under a free end of the optical cable.
If the problem persists, check the driver. On the console screen, open SCSI Adapters from the Control Panel. Click on the Drivers tab. You should see the following entry:
Emulex LP6000/LP7000/LP8000LP850, PCI-Fiber...(Started)
If the word "Started" does not appear, the driver has not started. If the driver has not started, go to the Readme.txt file that comes with the driver zip file from Emulex and read the section "MICROSOFT NT ISSUES/INFORMATION."
If the problem persists, and you have checked the following conditions:
This indicator lights on the back of the FC host adapter are normal,
The driver is started and sees the EMC Symmetrix as a device, but does not see any drives,
contact the EMC Symmetrix administrator to ensure that the Symmetrix ports are configured correctly.
If after all these steps the MQuad still does not recognize drives in the Symmetrix, you may have a defective host adapter board.
