Connectrix: Cisco DCNM web UI not correctly displaying proper enclosure names and all storage ports

Symptom 1: Hosts displaying links to each individual array port, but not seeing all the array ports under a single enclosure name in the web UI.

Symptom 2: peer fabric shows correctly, the same hosts and storage show a single enclosure for the storage ports.

Symptom 3: customer uses device-aliases with this general patter or syntax:

pr-xio0001-X*-SC*_target*

DCNM needs adjustment to the device alias enclosure creation expression in server.properties.

To resolve, follow these steps:

1. In web UI, edit the server.properties file for a list of regular expressions for alias->enclosure creation as follows.

   Note: This is adding a new expression to meet the device alias syntax the customer is using:

   Original entry:

   # ALIASES
   #
   # Use FC Zone Aliases instead of Device Aliases:
   fabric.fcalias=false
   
   # Automatically construct alias from WWN where none exists:
   # (No switch config performed.)
   fabric.autoAlias=true
   
   # List of Regular Expressions for alias->enclosure creation:
   # (Disable by commenting out property.)
   fabric.aliasRE=(.*)[_-]HBA.*,(.*)[_-]PCIE.*,(.*)[-_]ADAPTER.*,(.*)_TD.*,(.*)[-_]FCA.*,(.*)-QIP.*, (.*)[_-]JNI.*,(.*)[-_]QLA.*,(.*)-SLOT.*,(\w*)-\d.*,(\w*-[A-Z]\w*)-\d.*,(.*)[-_]FC.*

   Customer alias syntax: pr-xio0001-X*-SC*_target* (where * is a number)

   New expression for customer device alias syntax: (.*)[-_]X.*[-_]SC.*,

   Add the new expression to the beginning of the above fabric.alaisRE= expresion list:

   fabric.aliasRE= (.*)[-_]X.*[-_]SC.*,(.*)[_-]HBA.*,(.*)[_-]PCIE.*,(.*)[-_]ADAPTER.*,(.*)_TD.*,(.*)[-_]FCA.*,(.*)-QIP.*, (.*)[_-]JNI.*,(.*)[-_]QLA.*,(.*)-SLOT.*,(\w*)-\d.*,(\w*-[A-Z]\w*)-\d.*,(.*)[-_]FC.*

2. Restart DCNM server.

3. Once the DCNM server is back online, you can also manually edit the alias enclosure info in the DCNM San UI client:

   1. Launch DCNM SAN UI client.
   2. Open the wanted Fabric
   3. Click Hosts or Storage under Physical Attributes->End Devices
   4. Click the Enclosure Name field and click the Alias->Enclosure button on top. Click Apply from the dialog box to get the enclosure name changed.
   5. Click the green arrow on the top to apply the changes.

The customer can manually change the enclosure name in step 4 if they do not want to define their own regex patterns.
