EMC Host Connecivity with Emulex Fibre Channel HBAs and CNAs in the Windows Environment

Troubleshooting

Basic troubleshooting steps

You can follow this sample procedure for some basic troubleshooting

steps if your configuration is not working as expected. The procedure

below starts at the lowest layer in the host LUN detection sequence

and should be followed in order, moving to the next step only when

the current step appears correct.

1. Check that adapter has initialized, adapter driver is loaded, array

targets were discovered, and LUNs were discovered by the

adapter. This can be done in HBAnyware as follows:

• Verify adapter properties for driver loaded: Link Status should

be Operational or show a specific error to correct. Adapter

summary section should be complete and driver version

information correct.

• Adapters are shown in the left-hand window. Under each

adapter will be discovered targets as well as LUNs on each

target. This should match what is expected and should show

duplicate LUNs if multiple paths are enabled. If targets or

LUNs are missing, verify adapter zoning and array access

permissions/ LUN assignments.

2. If all items in step 1 above are as expected, verify that device

drivers are assigned correctly by Windows, and that all expected

devices are available. This can be done in the Windows Device

Manager as follows:

• Open the Device Manger as noted in “Starting device manager

for Windows” on page 166. Under disk drives there should be

one DGC or EMC disk listed for each device path available. If

disks are missing, recheck adapter zoning and access

permissions and ensure that LUNs are online from the array. If

LUNs appear in HBAnyware, but not in the device manager, it

is likely the LUNs are reported as offline by the array (or are

unavailable to Windows as inactive BCVs, etc.), or did not

have the correct drivers loaded by Windows. If the incorrect

disk drivers were loaded, the device may have a "!" beside the

icon, and viewing the device properties screen should indicate

the actual error.
