35 The scsi_log() function is a utility function that displays a message
36 via the cmn_err(9F) routine. The error levels that can be passed in to
37 this function are CE_PANIC, CE_WARN, CE_NOTE, CE_CONT, and SCSI_DEBUG.
38 The last level is used to assist in displaying debug messages to the
39 console only. drv_name is the short name by which this device is known;
40 example disk driver names are sd and cmdk. If the dev_info_t pointer is
41 NULL, then the drv_name will be used with no unit or long name.

43
44 If the first character in format is:
45
46 o An exclamation mark (!), the message goes only to the system
47 buffer.
48
49 o A caret (^), the message goes only to the console.
50
51 o A question mark (?) and level is CE_CONT, the message is
52 always sent to the system buffer, but is written to the con‐
53 sole only when the system has been booted in verbose mode.
54 See kernel(1M). If neither condition is met, the ? character
55 has no effect and is simply ignored.

58 All formatting conversions in use by cmn_err() also work with
59 scsi_log().

62 The scsi_log() function may be called from user, interrupt, or kernel
63 context.
