ESXi 5.x/6.0 Plugin Error codes

Code	Description	Status
P:0x0	No error.	VMK_SCSI_PLUGIN_GOOD
P:0x1	An unspecified error occurred. Note: The I/O cmd should be tried.	VMK_SCSI_PLUGIN_TRANSIENT
P:0x2	The device is a deactivated snapshot. Note: The I/O cmd failed because the device is a deactivated snapshot and so the LUN is read-only.	VMK_SCSI_PLUGIN_SNAPSHOT
P:0x3	SCSI-2 reservation was lost.	VMK_SCSI_PLUGIN_RESERVATION_LOST
P:0x4	The plug-in wants to requeue the I/O back. Note: The I/O will be retried.	VMK_SCSI_PLUGIN_REQUEUE
P:0x5	The test and set data in the ATS request returned false for equality.	VMK_SCSI_PLUGIN_ATS_MISCOMPARE
P:0x6	Allocating more thin provision space. Device server is in the process of allocating more space in the backing pool for a thin provisioned LUN.	VMK_SCSI_PLUGIN_THINPROV_BUSY_GROWING
P:0x7	Thin provisioning soft-limit exceeded.	VMK_SCSI_PLUGIN_THINPROV_ATQUOTA
P:0x8	Backing pool for thin provisioned LUN is out of space.	VMK_SCSI_PLUGIN_THINPROV_NOSPACE
