Acloud upgrade limitations

Newbie128272 Lv1Posted 26 Aug 2019 05:09

Dear all,

i'm reading the following guide: SANGFOR_aCloud_v5.8.6_aCloud5.8.6 Upgrade Guide.pdf

and i need some clarifications regarding following statements present on chapter 4:

2: do not support upgrade in three replica mode: so you cannot upgrade a cluster with this storage config?

4: upgrade is not supported when there are running or suspended virtual machines: do i need to shut down the whole cluster to upgrade?

5:upgrade is not supported when iscsi is connected please go to iscsi client to disconnect: do i need to detach every lux exported by acloud cluster  or every lun mounted by it?

are the above indicated statements general guidelines (valid for every upgrade) or only related to 5.8.6 upgrade?

thank you
