Hello All,We are currently testing a NFS+Sun Cluster solution with ZFS in our environment. Currently we have 2 HP DL360s each with a 2-port LSI SAS 9200-8e controller (mpt_sas driver) connected to a Xyratex OneStor SP1224s 24-bay sas tray. The xyratex sas tray has 2 ports on the controller which can connect to each server. We have a zpool of 2x (8+2) drives and 1 hot spare and also 3 intel X25-E ssds in the tray. We were hoping to have the ssds work as slog/cache devices however when we add them to the pool (as cache or log) we start to get an insane number of scsi resets. When the storage is connected to a single node the resets do not happen.scsi: [ID 107833 kern.warning] WARNING: /scsi_vhci/ d...@g50015179591cdd18 (sd24):Error for Command: write(10) Error Level: Retryablescsi: [ID 107833 kern.notice] ASC: 0x29 (power on, reset, or bus reset occurred), ASCQ: 0x0, FRU: 0x0Could this error be because the Intel SSDs are sata and we need a real SAS interface for multi-initiator support or is it a bug in the firmware somewhere that needs to be addressed? Where can we go from here to troubleshoot this oddity?
