    Posted 3 days ago

    Hi,

    Let's say I have a standard cluster in the primary datacenter using  FS5200  and second FS5200 in  diferent datacenter.
    Let's suppose I have remote copy between the two storages using FC. Storage in the primary DC is the production device.  
    I want to change  the primary FS5200  to  Hyperswap topology.
    1. When I change topology in primary DC this will afected to host connect it ?
    3.  What additional steps needed to do on the storage in secondary site to complete the config given this scene?
    2. Is it necessary to change the Storage ID of the secondary site? If this is possible how can I do it?

    Hi, 
     
    1- what is your code level?
    2- what is the bandwidth between two datacenters and how it's connected (san switch isl - direct lw sfp via dark fibre or dwdm)
    3- if you upgrade your 5200 boxes to the latest code level (8.7), you can do it with Policy Based HA configuration. In legacy hyperswap, you cannot create a hyperswap relationship between two independent 5200s.

    Hi,

    1. 8.4
    2. Bandwith betweeen two DCs  is 16GB via dark fiber connected san switch isl 
    3. Policy based HA configuracion  is non-viable for us now.
    4. All prerequisites are meet, (lw sfp, dark fiber, all zoning )  
    5. Currently remote copy with Global Mirror work over  dark fiber using san switch.

    Hi Wilfrido,

    First of all you need to upgrade newer LTS level (8.5.0.12 - 8.6.0.4 or 8.7.0.0) . If PBHA is non-viable for you, you must first delete the existing replication configuration, then delete the configuration in the 2nd box and reset the 2nd 5200. If you are unfamiliar with doing this, you may want to ask a professional to help. 

    notes:

    • 8.4 will EoS on 31 Dec 2024
    • if you are using isl between sites check the isl requirements for Hyperswap at IBM Docs
    • To better understand hyperswap,  I recommend you also watch this video. 

    You can always contact me if you have any questions.
