A.6.1.2 Obtaining Logs
This command is used to obtain vendor logs from the SSD. Each command sent from the host
can obtain a maximum of 4KB of logs. The host obtains the total log size through the vendor
log length query command (SubOpCode 0x21h) and then sends commands repeatedly to
obtain all logs. Besides the total data size, the commands must also specify an offset value,
where 1 indicates 4 KB.
Sub_OpType indicates the log type.
