Virtual SCSI HBA Subsystem Does Not Support All SCSI Enclosure Services Devices
An SES device that is seen by the Oracle Solaris OS as a secondary function is an SES device type that cannot be supported by vhba
. vhba
can support an SES device whose device type has a value of 0xd
as specified in the inq_dtype
field of the INQUIRY
payload.
When the vhba
binary in the guest domain attempts to initialize some SCSI enclosure services (SES) devices, vhba
causes scsi
to issue the following warning message:
... scsi: WARNING: scsi_enumeration_failed: vhba2 probe@w50080e51bfd32004,0,d enumeration failed during tran_tgt_init
The ,d
substring represents the 0xd
hexadecimal digit, which is the SCSI industry standard code for an SES device. The ,d
string indicates that this warning message is a result of an unsupported type of SES device.
vhba
can support an SES device that has a device type of 0xd
that is specified in the inq_dtype
field of the INQUIRY
payload:
