cannot create partnership between FS5300 using fiber channel connection

  • 1.  cannot create partnership between FS5300 using fiber channel connection

    Posted Tue September 09, 2025 11:13 AM

    Hi, 

    The two system can see each other via the SAN zonning. I dedicated 2 port per nodes for the system to system connection and i can see those in 'connectivity'.

    When it try to create a partnership (or an HA policy) there is no proposal (the selection is empty and the create partnership button is not there). i'm running 9.1.0.1

    Can i have some help ?

    Could it be possible that the FS5300 systems have layer : storage (instead of replication)? 

    Yuo can check this with lssystem | grep layer 

    IBM_FlashSystem:FS5300:superuser>lssystem | grep layer
    layer replication

    Both as 'layer replication'

    Next thing I would check is partner_fc_port_mask found with cli command lssystem

    i have those values on both system:

    partner_fc_port_mask 1111111111111111111111111111111111111111111111111111111111111100
    partnership_exclusion_threshold 315

    I don't know which 2 ports you want to use for replication, but perhaps you could try to include port 1 and 2 in the port_mask as well.

    Just to check, did you use the physical ports for zoning?

    I agree with last comment from T Masteen,

    Did you use WWPNs from Host IO permitted = yes ? Check your WWPNs with command lstargetportfc?

    Yes i use the physical port

    Effective configuration:
     cfg:   ProA
     zone:  QOSH1_FS5300_INTERCONNECT
                    50:05:07:68:12:13:9f:a1
                    50:05:07:68:12:13:9f:9f
                    50:05:07:68:12:13:a2:b0
                    50:05:07:68:12:13:a2:af

    It seems is not possible to create partnership or HA storage partition using the GUI (no button, empty selection box) when using fiber channel as interconnect despite the cli command 'lspartnershipcandidate' showing the remote storage (may be i did something wrong but did not find the cause)

    I succeeded to configure the HA using cli command. Here the procedure

    1. share certificates

      https://www.ibm.com/docs/en/flashsystem-5x00/9.1.0?topic=replication-partnerships
      use scp/sftp to copy certificate over
      
      chsystemcertstore -export -scope internal_communication
      mktruststore -file /tmp/certificate.pem -restapi on -name <remote_cluster_name>

    2. create partnership

      https://www.ibm.com/docs/en/flashsystem-5x00/9.1.0?topic=partnerships-using-fibre-channel-connectivity

      mkfcpartnership -linkbandwidthmbits <link_bandwidth_in_mbps> -backgroundcopyrate <percentage> <remote_system_id | remote_system_name>

    3. reset replication pool id of both storage

      chmdiskgrp -resetreplicationpoollinkuid <pool_id)

    4. link pool with the volume policy

      https://www.ibm.com/docs/en/flashsystem-5x00/9.1.0?topic=replication-pool-links

    5. create quorum jar for partner, upload then deploy quorum

      https://www.ibm.com/docs/en/flashsystem-5x00/9.1.0?topic=quorum-ip-application
      use ftp/scp to retreive the jar file in /dumps directory

      mkquorumapp -partnersystem <remote system ID or name>

    6. create a replicationpolicy

      mkreplicationpolicy -topology 2-site-ha -location1system <name or ID of one system> -location1iogrp 0 -location2system <name or ID of other system> -location2iogrp 0

    7. create the storage partition with the replicationpolicy

      mkpartition -name ha_partition -replicationpolicy <HA policy ID or name>

    can you please share the output of below command

    svcinfo lsclustercandidate -gui
