scsi_log() is a utility function that displays
a message via the cmn_err(9F) routine.
The error levels that can be passed in to this function are CE_PANIC, CE_WARN, CE_NOTE, CE_CONT, and SCSI_DEBUG. The last level is
used to assist in displaying debug messages to the console only. drv_name is the short name by which this device is known; example
disk driver names are sd and cmdk.
If the dev_info_t pointer is NULL, then the drv_name will be used
with no unit or long name.
If the first character in format is:
- An exclamation mark (!), the message
goes only to the system buffer.
- A caret (^), the message
goes only to the console.
- A question mark (?) and level is CE_CONT, the message is always sent
to the system buffer, but is written to the console only when the system
has been booted in verbose mode. See kernel(1M).
If neither condition is met, the ? character has no effect
and is simply ignored.
All formatting conversions in use by cmn_err()
also work with scsi_log().

scsi_log() may be called from user or interrupt
context.
|
| | Example 1.
| |
| |
scsi_log(dev, "Disk Unit ", CE_PANIC, "Bad Value %d\n", foo);
|
generates:
| |
PANIC: /eisa/aha@330,0/cmdk@0,0 (Disk Unit 0): Bad Value 5
|
This is followed by a PANIC.
|
Example 2.
| |
| |
scsi_log(dev, "sd", CE_WARN, "Label Bad\n");
|
generates:
| |
WARNING: /sbus@1,f8000000/esp@0,8000000/sd@1,0 (sd1): Label Bad
|
|
Example 3.
| |
| |
scsi_log((dev_info_t *) NULL, "Disk Unit ", CE_NOTE, "Disk Ejected\n");
|
generates:
|
Example 4.
| |
| |
scsi_log(cmdk_unit, "Disk Unit ", CE_CONT, "Disk Inserted\n");
|
generates:
|
Example 5.
| |
| |
scsi_log(sd_unit, "sd", SCSI_DEBUG, "We really got here\n");
|
generates (only to the console):
| |
DEBUG: sd1: We really got here
|
