I need to see Redundancy / Failover of the HBA`s connected to the SAN.
I am new to Storage and have run the SAN Health audit V3.2
Can someone plz tell me "How to" interpret the report to specifically see If the various HBA`s connected have redundancy.

If you look at the SAN health spreadsheet, you will find sheets specific to zoning in the different fabrics. Look for aliases that represent the host and manually verify if the hosts are connected redundantly. For example one of our servers 6162 has 2 HBA's
But this really depends on whether your colleagues have followed naming conventions during creation of aliases.
Also look at the VISIO diagram that you might have got, you can verify visually if your host has two connections, this is simple and faster.

Thank you for your reply,
here is an example i pulled :
Does the above imply dual redundancy?

this shows ur Storage is zoned with HBA-example in Fab-1, this is difficult to find unless u find the WWNs of the HBAs, if ur colleagues have given HBA names liek SERVERNAME_HBA1, it should be like this , then it will be easy otherwise WWNs are only identification. in visio u can find it.

jassat_a if you dont mind posting your SAN health report maybe I can give you a clue. Else look at the VISIO diagram and judge.
Remove spaces from the filename, else I wont be able to download it. There is a problem with the forum software.

i've looking the report..... and just a stupid Tipp....
Make sure MPIO is correct configured and enable for DUAL Port HBA.
This can be the reason Redundancy / Failover is not reported in SAN Health.
If you are satisfied with the responses please mark as 'Answered'.
If not, just let me know I can see to get more info.
I would appreciated if you rate the threads.

Well most of your servers are dual connected and as ABBA mentioned they have more than 2 HBA ports.
Look at sheet Z_SHODENPROD1-6069806cac
then scroll down and ensure that its zoned with the storage
On the other fabric Z_SHODENPROD2-6069806cad, you will find the other entry
But on closer inspection you will find that although the alias exists the WWPN is not physically logged in. It might be possible that you guys replaced the HBA with a different one or maybe its faulty. Observe the color of both the alias and the zone they both are aqua.
Now example of a single connected server would be your NIM server
It does not have another leg in PROD2 fabric.
Since you are HDS shop, you might have HDLM installed for multipathing. You can type in
dlnkmgr view -path
on the hosts and find out whether they are dual path on single, easier and better. And one step further you can buy HGLAM or check if its already in your contract and monitor all host paths from a single console.
