Hey there I am just looking for a way to find a corrupt tar file. I want to write a script to help sift through the 1000's of tar files we go through daily and move any corrupt ones to a different directory structure. Is there an easy way to do this. (4 Replies)
Hello, I am currently dumping 30-40 reports on a Unix folder located here /home/apps/reports/prode/excel
I use K-shell to do this task. In that, I use the gzip command to compress these files. I want to be able to use a tar command to first load the entire directory into one file then gzip that... (2 Replies)
I've got a KSH/AIX question that I haven't been able to figure out yet.
I've got a tape archive program that "tar's" data to a tape. After creating the archive, I'd like to somehow verify that the tape is actually good. So, what I'd like to do as a simple "sanity" check that I can read the tape... (9 Replies)

scsi_errmsg
scsi_errmsg(9F) Kernel Functions for Drivers scsi_errmsg(9F)NAME
scsi_errmsg - display a SCSI request sense message
SYNOPSIS
#include <sys/scsi/scsi.h>
void scsi_errmsg(struct scsi_device *devp, struct scsi_pkt *pktp, char *drv_name, int severity, daddr_t blkno, daddr_t err_blkno, struct
scsi_key_strings *cmdlist, struct scsi_extended_sense *sensep);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
PARAMETERS
devp Pointer to the scsi_device(9S) structure.
pktp Pointer to a scsi_pkt(9S) structure.
drv_name String used by scsi_log(9F).
severity Error severity level, maps to severity strings below.
blkno Requested block number.
err_blkno Error block number.
cmdlist An array of SCSI command description strings.
sensep A pointer to a scsi_extended_sense(9S) structure.
DESCRIPTION
scsi_errmsg() interprets the request sense information in the sensep pointer and generates a standard message that is displayed using
scsi_log(9F). The first line of the message is always a CE_WARN, with the continuation lines being CE_CONT. sensep may be NULL, in which
case no sense key or vendor information is displayed.
The driver should make the determination as to when to call this function based on the severity of the failure and the severity level that
the driver wants to report.
The scsi_device(9S) structure denoted by devp supplies the identification of the device that requested the display. severity selects which
string is used in the "Error Level:" reporting, according to the following table:
Severity Value: String:
SCSI_ERR_ALL All
SCSI_ERR_UNKNOWN Unknown
SCSI_ERR_INFO Informational
SCSI_ERR_RECOVERE Recovered
SCSI_ERR_RETRYABL Retryable
SCSI_ERR_FATAL Fatal
blkno is the block number of the original request that generated the error. err_blkno is the block number where the error occurred. cmdlist
is a mapping table for translating the SCSI command code in pktp to the actual command string.
The cmdlist is described in the structure below:
struct scsi_key_strings {
int key;
char *message;
};
For a basic SCSI disk, the following list is appropriate:
static struct scsi_key_strings scsi_cmds[] = {
0x00, "test unit ready",
0x01, "rezero/rewind",
0x03, "request sense",
0x04, "format",
0x07, "reassign",
0x08, "read",
0x0a, "write",
0x0b, "seek",
0x12, "inquiry",
0x15, "mode select",
0x16, "reserve",
0x17, "release",
0x18, "copy",
0x1a, "mode sense",
0x1b, "start/stop",
0x1e, "door lock",
0x28, "read(10)",
0x2a, "write(10)",
0x2f, "verify",
0x37, "read defect data",
0x3b, "write buffer",
-1, NULL
};
CONTEXT
scsi_errmsg() may be called from user or interrupt context.
EXAMPLES
Example 1: Generating error information.
This entry:
scsi_errmsg(devp, pkt, "sd", SCSI_ERR_INFO, bp->b_blkno,
err_blkno, sd_cmds, rqsense);
Generates:
