After updating to Oracle Solaris 11.1 SRU 17.5 or later, the system displays the following warnings frequently on the console:
Mar 21 16:23:41 nova scsi: [ID 107833 kern.notice] /pci@0,0/pci8086,3c0a@3,2/pci1000,3050@0 (mpt_sas0) Mar 21 16:23:41 nova ext-arq alloc fail. addr 0, size e80 Mar 21 16:23:41 nova scsi: [ID 107833 kern.warning] WARNING: /pci@0,0/pci8086,3c0a@3,2/pci1000,3050@0 (mpt_sas0) Mar 21 16:23:41 nova alloc_extra_sgl_frame failed
Workaround: Ignore the warnings. The warnings are not fatal because the scsi packets are resent after the delay.
