scsi_log(9F)

NAME

scsi_log − display a SCSI-device-related message

SYNOPSIS

#include <sys/scsi/scsi.h> #include <sys/cmn_err.h>

void scsi_log(dev_info_t ∗dip, char ∗drv_name, u_int level, const char ∗fmt, ...);

INTERFACE LEVEL

Solaris DDI specific (Solaris DDI).

ARGUMENTS

dip Pointer to the dev_info structure.

drv_name String naming the device.

level Error level.

fmt Display format.

DESCRIPTION

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 point), the message goes only to the system buffer. If the first character in format is a ’^’ (circumflex), the message goes only to the console. If the first character is a ’?’ (question mark), and level is CE_CONT, the message is always sent to the system buffer, but is only written to the console 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().

CONTEXT

scsi_log() may be called from user or interrupt context.

EXAMPLES

a.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.

b.scsi_log(dev, "sd", CE_WARN, "Label Bad\n"); Generates:

WARNING: /sbus@1,f8000000/esp@0,8000000/sd@1,0 (sd1): Label Bad

c.scsi_log((dev_info_t ∗) NULL, "Disk Unit ", CE_NOTE, "Disk Ejected\n"); Generates:

Disk Unit: Disk Ejected

d.scsi_log(cmdk_unit, "Disk Unit ", CE_CONT, "Disk Inserted\n"); Generates:

Disk Inserted

e.scsi_log(sd_unit, "sd", SCSI_DEBUG, "We really got here\n"); Generates (only to the console):

DEBUG: sd1: We really got here
