HCP: Rolling Firmware upgrade impossible?

Hi,

after some tests we found that HCP doesnt support a single node upgrade while online when talking about a HCP 500 system with nx4 nodes and RAID6 HUS150 in Background on DPL = 1? During Fimrwareupgrade the HCP node that is in upgrade doesnt do failover to the other node during upgrade so all local data to this node is inaccessable for users.

 

Keep in mind that HCP can be a 80PB plattform with 40 nodes - shutting down parts of the cluster is impossible so my question is if there are any activities to get around this issue?

 

Thanks in advance

 

Matthias
