  31. Abstract: Tagged command queuing disabled for SCSI-2 and SPC targets
  32.  
  33. *** 09/30/16 08:55 am ***
  34. Degraded performance for the mpt related disks in a Solaris 11.2 VMware guest
  35. with a MPT HBA (emulated device). The sd drivers sends 1 I/O at a time to the
  36. disk.
  37.  
  38. On Solaris 10 with the same guest VMware domain with MPT device, there is not
  39. such issue.
  40.  
  41. The tag command queueing is disabled on S11.2 while it is active on 10. This
  42. is visible at iostat and in the sd and mpt related data.
  43.  
  44. The same MPT device, same FW version is reported for both guest domains.
  45.  
  46. The differences in mpt configuration is visible with :
