delete dasd_id, it moved to s390-tools
These s390-tools-1.6.0 (applicable for the "October 2005 stream") replace s390-tools-1.5.4.
New tools:
* tape390_crypt: Tool to control and query crypto settings for 3592 zSeries tape devices.
* mon_fsstatd: Daemon that writes filesystem utilization data to the z/VM monitor stream.
* dumpconf: Allows to configure the dump device used for system dump in case a kernel panic occurs.
* dasdinfo: Display unique DASD ID, either uid or volser.
* 59-dasd.rules: udev rules for unique DASD device nodes created in /dev/disk/.

.TH DASD_ID 8 "November 2005" "" "Linux Administrator's Manual"
|
||||
.SH NAME
|
||||
dasd_id \- udev callout to read label from s390 block device
|
||||
.SH SYNOPSIS
|
||||
.BI dasd_id
|
||||
[\fI--export\fP] \fIblockdevice\fP
|
||||
.SH "DESCRIPTION"
|
||||
.B dasd_id
|
||||
is normally called from a udev rule, to provide udev with a unique string and
|
||||
additional information (type, serial) for an S390 drive. Udev can use this
|
||||
information to create symlinks in /dev/disk/by-id and /dev/disk/by-label
|
||||
to the real device node.
|
||||
.SH USAGE
|
||||
.B dasd_id
|
||||
opens the blockdevice node specified at the commandline and prints the
|
||||
information chosen by the options.
|
||||
.SH OPTIONS
|
||||
The following commandline switches are supported to specify what dasd_id
|
||||
should print:
|
||||
.TP
|
||||
.BI --export
|
||||
print all values (instead of only the serial)

||||
