README for sg3_utils/scripts + ============================ +Introduction +============ +This directory contains bash shell scripts. Most of them call one or +more utilities from the sg3_utils package. They assume the sg3_utils +package utilities are on the PATH of the user. + +rescan-scsi-bus.sh is written by Kurt Garloff (formerly from Suse Labs) +with patches from Hannes Reinecke (Suse) and Redhat. + +scsi_logging_level is written by Andreas Herrmann <aherrman at de dot ibm +dot com>. It sets the logging level of the SCSI subsystem in the Linux +2.6 series kernels. See that file for more information. + +The other scripts are written by the author. Some do testing while others +do bulk tasks (e.g. stopping multiple disks). + +Details +======= +Each script supplies more information, typically by supplying a '-h' +or '--help' option. The script source often contains explanatory +information. Following is a usage summary with a one line description: + rescan-scsi-bus.sh [OPTIONS] + - see the output of 'rescan-scsi-bus.sh --help' + scsi_logging_level [OPTIONS] + - set Linux SCSI subsystem logging level + scsi_mandat [-h] [-L] [-q] <device> + - check for mandatory SCSI command support + scsi_readcap [-b] [-h] [-v] <device>+ + - fetch capacity/size information for each <device> + scsi_ready [-h] [-v] <device>+ + - check the media ready status on each <device> + scsi_satl [-h] [-L] [-q] [-v] <device> + - check <device> for SCSI to ATA Translation Layer (SATL) + scsi_start [-h] [-v] [-w] <device>+ + - start media (i.e. spin up) in each <device> + scsi_stop [-h] [-v] [-w] <device>+ + - stop media (i.e. spin down) in each <device> + scsi_temperature [-h] [-v] <device>+ + - check temperature in each <device> + +These scripts assume that the main sg3_utils utilities are installed +and are on the user's PATH. + +This directory, prior to sg3_utils-1.28, contained the sas_disk_blink +script. Since it depends on the sdparm utility it has been moved to +the sdparm package in its scripts directory. + +59-scsi-sg3_utils.rules is a Linux specific file for udev. These rules use +'sg_inq --export' to help udev create identifying device nodes, for example +/dev/disk/by-id/wwn-0x5001501234567890-part1. + +Douglas Gilbert +4th October 2021 diff --git a/scripts/cciss_id b/scripts/cciss_id new file mode 100755 index 00000000..8ac11d5f --- /dev/null +++ b/scripts/cciss_id @@ -0,0 +1,66 @@ +#!/bin/bash +# +# cciss_id +# +# Generates device node names according to the cciss naming rules +# +# Copyright (C) 2011 SUSE Linux Products GmbH +# Author: +# Hannes Reinecke <hare@suse.de> +# +# +# This program is free software;
