Hi Team, We run Apache CloudStack 4.22.1.1 on KVM with HPE storage that speaks the in-tree Primera WSAPI (Alletra Storage MP / Primera / 3PAR / Alletra 9000. Not Nimble OS). The array is presented over iSCSI, not Fibre Channel.
Pool create, VV lifecycle, and volume snapshots work with Provider = Primera. Attach on the hypervisor does not: stock scripts/storage/multipath/connectVolume.sh waits on /sys/class/fc_host, which is empty on an iSCSI-only host, so the LUN never shows up. The shared target IQN also must not be logged out when one volume detaches (many VLUNs on one session). We published a small overlay for 4.22.1.1 (Apache 2.0, derived from the in-tree scripts and Primera adapter): https://github.com/dahampere/cloudstack-primera_alletraMP-iscsi Release: https://github.com/dahampere/cloudstack-primera_alletraMP-iscsi/releases/tag/v4.22.1.1-1 - KVM deb: iSCSI session rescan + no logout on detach (this is the actual fix). - Optional management sidecar JAR: same adapter registered as AlletraMP, so you can add a pool under that name without renaming an existing provider=Primera pool. Not a second API. Not ACS Protocol = iSCSI (shared LUN). Proven here: deploy, attach/detach, live migrate, volume snapshot. Volume resize/copy on this path is unproven. Instance snapshots still need qemu-guest-agent. If this matches other KVM + Primera-family iSCSI sites, we are happy to turn the connect/disconnect change into an upstream PR against scripts/storage/multipath. Feedback welcome.
