HBA login issue with Cisco and HP switcs
Hello to all,
I have a HP C-7000 blade system with below configuratin.
- BLC7000 system
- 8 x HP BLC480c blade servers
- HP BLC Emulex LPe1105 FC HBA
- 2 x Cisco MDS 91924e SAN switch
I have a CX4-120 and when I connect the fron-ports of CX4 to MDS 9124E switch, it works fine but when I connect the MDS 9124E to anolther external HP StorageWork 2/8V ( Boracade Silkworm 3250 ) using E_ports, then the HBAs will not shown in Navisphere and they can't login to CX4-120.
Also be informed that the LED of E_pots in HP 2/8V switched slowly flashing green which it means "loopback cable or incompatible switch).
I just want to know what is the problem ? and how can I resolve this?
If MDS 9124E and HP 2/8V are not compatible? or maybe the HP 2/8V (Boracade Silkworm 3250 ) is not full fabric licensed and can't support connect to more than 2 switches. Because already 2 HP 2/8V switches are stacked now.
Looking any help.
Hi,
Thanks for your answer. I am new to Cisco switch and
I don't know how and where I can find intreoperability setting for ILS between cisco 9124E and brocade silkworm 3250.Just be informed that HBAs are Emulex not Qlogic and also they mapped through cisco switch not brocade. If I bypass brcades then everything is ok but when I use ISL between brocades and cisco there is no HBA loging in.
I think aslo brocades license be an issue because both brocades stack to each other dependently one of them domain 1 and another domain 2 and the cisco is domain 3.
So if brocades has not full fabric license so there is an issue here because the license will not permit to set fabic with 3 swtiches. Am I right?
- according to E-Lab the only mode supported on 9124e is the NPV mode. In this mode your 9124e will not be joining the fabric, it will be acting as a pass-through. Please research requirements for your brocade switch, i think it needs to support NPV mode as well.
- you need to upgrade 3250 to 5.3.2c ..if it's supported by EMC you will need to contact your EMC CE otherwise get it from Brocade. When i looked at FOS 5.3.2 admin guide i did not see any references for NPV just NPIV so this is something that you need to verify with EMC/Brocade.

Hi,
Qlogic HBAs from Blade Server are internally connected/mapped to these Brocade's. So, to connect that to SAN via Cisco FC 9124 you have to do either ISL or Access Gateway setup. Full Fabric lincese issues doesn't seems to be there as that is needed in case of trunking. Also, the two Brocade's are independently stacked. For ISL, one also needs to check the FOS and SAN-OS versions compatibility of Brocade and MDS and few other interOp settings needs to be checked.
Also, If you can ask the vendor(HP) to replace the Brocade's with FC Bypass modules(Emulex make), then the connectivity of Blade to SAN will be straightforward.
Thanks
