If the multi-path configuration is incorrect or there is only one link, Io will be interrupted.Īfter changing the battery, reset the battery to allow the Controller to recognize it again. If you configure multi-path, Io will not be interrupted. Will the production Io be interrupted during switching? You can download it if you need to read it. Switch all arrays to Controller 1, offline controller 2, remove controller 2, replace the battery, insert it back to online, and reset the new battery. The Management ports of ds4700 controllers must be connected, you can connect the management ports and laptops of the two controllers to one dummies switch to ping the default Management IP address.Ģ. Use the SM software to log on to the ds4700 management interface. DS series now has that capability, through a very specific set. Here we record the replacement steps and precautions strong demand for support of Apple servers and work stations with IBM DS series storage. Today, the customer's ds4700 storage has replaced the battery. On newer Linksys routers, both the default username and the default password are set to admin. Generally, the life of the storage battery is 3 years. Pwwn 20:06:00:a0:b8:26:7b:c9 targetĪnd more simple question - as far as I know MDS9148 do not have LUN zoning after 5.The storage controller uses a battery to ensure that data in the cache can be written to the hard disk without being lost in the case of an unexpected power failure. Is there any way to combine switch fabric and array fabric to allow traffic from one host go through any link between switch and array? Array show itself as different port wwns (on each link) and one node wwn.ĭoes host connect port-to-port or it can connect port-to-node? Something like port-channeling or domain joining or maybe switch can proxy array node ports behind itself. This is the least possible traffic distribution configuration which apparently seem to be non-fault tolerant and also one of the links can be overloaded some day. Ibm Ds4700 Conguration Guide - Ibm Ds4700 Conguration Guide - DS4700 Storage Server - Tech Data IBM System Storage DS4000 and Stor-age Manager V10.30 IBM. I have managed to connect all ports (two ports from two controllers) from DS4700 to DS9148 and I use zoning to connect host ports to different array ports. I want to utilize IBM DS4700 disk array with Cisco DS9148 switch, serving multiple hosts.
