I have two IBM DS 5020 san. I have also mirroring on them. Or had. Until I moved one of the in another data center. It seems that I cannot enable the mirroring again.
Between the datacenters I have black fiber. So a fabric over 50 km. But it works fine. All licenses are in place, configuration ok. I have two links actually between the data centers. But one of them is up.
For the DS, I connect FC port used for mirroring to the san switch. I see that both SAN communicate with the fiber switches. I see the WWNs. So I have created the connection betwen them.
Here is the configuration for each san switch port used by the SAN.
Area Number: 9Speed Level: 4GFill Word: 1(Arbff-Arbff)AL_PA Offset 13: OFFTrunk Port ONLong Distance OFFVC Link Init OFFLocked L_Port OFFLocked G_Port OFFDisabled E_Port OFFLocked E_Port OFFISL R_RDY Mode OFFRSCN Suppressed OFFPersistent Disable OFFLOS TOV enable OFFNPIV capability ONQOS E_Port AEPort Auto Disable: OFFRate Limit OFFMirror Port OFFCredit Recovery ONF_Port Buffers OFFFault Delay: 0(R_A_TOV)NPIV PP Limit: 126CSCTL mode: OFF
I have tried with WORDFILL having values 0 and 3. Did not work.
The error i get is 180 - cannot communicate with the remote storage subsystem to complete this request.
Any tips much appreciated.
To mention that the GBICs i am using are Brocade 8Gb. But I have configured the speed to be 4 Gb, as the controller supports. I have tried with 8 Gb as well. Does not work. Were 4 Gb before, but I do not think that this should be an issue.
And one mor thing. On the main SAN, I see two small Logical Drives called MIRROR REPOSITORY. Should those be deleted?
Before moving the SAN, I have stopped the mirroring process. Not suspended, but stoped.
My mistake. I have mixed the controllers. A has to speak with A and B has to speak with B.
did you mean that only mistake that you had is mixing on zoning controlars A & B?
i have the same issue and need your help
