The T10 VENDOR IDENTIFICATION field contains eight bytes of left-aligned ASCII data identifying the vendor of the product. The T10 vendor

ERROR TYPE field
The ERROR TYPE field (see table 231) specifies the error detected by the application client.
CLR bit
If the CLR_SUP bit is set to one in the error history directory parameter data (see 3.70.15), a CLR bit set to one specifies that the
device server shall:
a) clear the portions of the error history that the device server allows to be cleared; and
b) ignore any application client error history specified in the parameter list.
If the CLR_SUP bit is set to one in the error history directory parameter data, a CLR bit set to zero specifies that the device server
shall not ignore the
CLR bit.
If the CLR_SUP bit is set to one in the error history directory parameter data, a CLR bit set to zero specifies that the device server
shall:
a) not clear the error history; and
b) process all application client error history specified in the parameter list.
If the CLR_SUP bit is set to zero in the error history directory parameter data, the device server shall ignore the CLR bit.
TIME STAMP field
The TIME STAMP field shall contain:
a) a time based on the timestamp reported by the REPORT TIMESTAMP command, if the device server supports a device
clock (see SPC-5)
b) The number of milliseconds that have elapsed since midnight, 1 January 1970 UT; or
