The static analysis tool for Debian packages 'lintian', especially if called like 'lintian -EvIL +pedantic', checks manual pages for correctness and typos. This commit fixes typos that were identified by lintian and marked with 'typo-in-manual-page' while s390-tools version 2.20.0 was packaged.

.TH DASDINFO 8 "Febr 2007" "s390-tools" "Linux Administrator's Manual"
|
|
.SH NAME
|
|
.B "dasdinfo "
|
|
\- tool to read unique id from s390 DASD device
|
|
.SH SYNOPSIS
|
|
.BI "dasdinfo [-a] [-l] [-u] [-x] [-e] {-i " <busid>
|
|
.BI "| -b " <blockdev>
|
|
.BI " | -d " <devnode>
|
|
.BI "}"
|
|
.sp
|
|
.BI "dasdinfo [-h] [-v]"
|
|
|
|
.SH DESCRIPTION
|
|
.B dasdinfo
|
|
displays specific information about a specified DASD device.
|
|
It is normally called from a udev rule, to provide udev with a unique id string and
|
|
additional information (type, serial) for an S390 DASD 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 OPTIONS
|
|
|
|
.TP
|
|
.BI "-a|--all"
|
|
Same as -u -x -l
|
|
.TP
|
|
.BI "-x|--extended-uid"
|
|
Print DASD uid
|
|
|
|
This option prints the full uid of the DASD. When z/VM provides two
|
|
virtual devices that are actually located on the same real device, the
|
|
first four tokens of the uid will be identical for both devices. z/VM
|
|
may provide an additional token that can be used to distinguish between
|
|
different minidisks. You need both support in the Linux kernel and
|
|
z/VM to receive such an additional token.
|
|
|
|
For z/VM: VM support for the hypervisor injected Special Node Element
|
|
Qualifier (SNEQ) (or hypervisor injected self-description data) is
|
|
available by applying the PTFs for VM APAR VM64273 on z/VM 5.2.0 and higher.
|
|
.TP
|
|
.BI "-u|--uid"
|
|
Print DASD uid without z/VM minidisk token
|
|
|
|
z/VM may provide an additional token that can be used to distinguish
|
|
between different minidisks (see --extended-uid option). To remain
|
|
compatible with systems that were installed on older Linux or z/VM
|
|
levels, the -u option will print the uid excluding any z/VM-provided
|
|
minidisk token.
|
|
|
|
For example, if the extended uid is
|
|
IBM.75000000092461.e900.10.00000000000037400000000000000000 then the
|
|
uid is IBM.75000000092461.e900.10. If the extended uid contains no
|
|
minidisk token, e.g. in an LPAR environment, then both uids are the
|
|
same.
|
|
.TP
|
|
.BI "-l|--label"
|
|
Print DASD volume label (volser).
|
|
.TP
|
|
.BI "-i|--busid " <busid>
|
|
Use the bus ID as input parameter, e.g. 0.0.e910.
|
|
.TP
|
|
.BI "-b|--block " <blockdev>
|
|
Use the block device name as input parameter, e.g. dasdb.
|
|
.TP
|
|
.BI "-d|--devnode " <devnode>
|
|
Use a device node as input parameter, e.g. /dev/dasdb.
|
|
.TP
|
|
.BI "-e|--export"
|
|
Print all values (ID_BUS, ID_TYPE, ID_SERIAL).
|
|
.TP
|
|
.BI "-h|--help"
|
|
Print usage text.
|
|
.TP
|
|
.BI "-v|--version"
|
|
Print version number.
|
|
|
|
.SH EXAMPLES
|
|
dasdinfo -u -i 0.0.e910
|
|
|
|
dasdinfo -u -b dasdb
|
|
|
|
dasdinfo -u -d /dev/dasdb
|
|
|
|
All three examples should return the same unique ID for
|
|
the same DASD device, e.g. IBM.75000000092461.e900.10.
|
|
|
|
In case this uid is not available, dasdinfo will return
|
|
the volume label instead, e.g. 0XE910.
