Причина
PowerStoreOS 3.5.0.x (and greater) do not handle replication of volumes of a 4k sector size properly if the transport protocol in use is iSCSI. Volumes with a 4k sector size replicate properly between clusters if the transport protocol in use is defined to use TCP (iBasic).
Разрешение
Configure PowerStore to use the connectivity type of TCP (iBasic) for volumes with a 4k sector size.
