I have a Linux server with 2 HBAs with 2 ports on each HBA. HBAs ports are zoned to netapp as well as ibm storage.
Is it recommended ?
Zoning something like below:
HBA1 - IBM Controller1a
HBA2 - IBM Controller2a
HBA1 - IBM Contolller1b
HBA2 - IBM Controller2b
HBA1 - Netapp Contoller1
HBA2 - Netapp Contoller2
I have been facing many multipaht issue. so wondering if zoning should follow best practices!
ANy help would be highly appreciated.
I agree with Alexey and I fear that even the most granular zoning won't save you from multipathing problems. That's most probably something you need to solve on the host itself.
I agree with Seb. This is not a SAN issue. Most often the hosts multipath.conf is setup incorrectly not differentiatig between the different device types. This causes conflicts.
This is not a SAN issue but more a Linux configuration problem.
Thanks Guys. Actually zones are not independent.
Brocade Sw1 Zone 1: ServerHBA1_IBM_N1_N2_P1
Brocade Sw2 Zone 12 ServerHBA2_IBM_N1_N2_P2
Cisco Sw1 Zone1: ServerHBA1_NetappN1_N2_P1
Cisco Sw2 Zone 2: ServerHBA2_NetappN1_N2_P2
Single HBA with dual port where P1 is going to brocade switch and P2 is going to cisco switch
