NAME¶
lszfcp - list information about zfcp adapters, ports, and unitsSYNOPSIS¶
lszfcp [-hvVaHDP] [-b busid] [-l lun] [-p wwpn] [-s /path/to/sys]DESCRIPTION¶
lszfcp provides information contained in sysfs about zfcp adapters, ports and units and its associated scsi_hosts, fc_hosts, fc_remote_ports and scsi_devices.The default is to list busids of all zfcp adapters and their corresponding SCSI host names.
There are three output variants. Default (without options "-a" or "-V") is one line for each object. For adapters the busid and their corresponding SCSI host names are listed. For ports the pair "busid"/"wwpn" and their corresponding FC-remote-port names are listed. For units the triple "busid"/"wwpn"/"lun" and their corresponding SCSI device names are listed.
Option "-V" additionally shows the sysfs paths of interest for the listed object.
Option "-a" additionally shows all attributes of interest found in sysfs for the listed object.
OPTIONS¶
- -a, --attributes
- Show all attributes of the specified objects.
- -D, --devices
- List zfcp units and SCSI devices.
- -H, --hosts
- List zfcp adapters and fc-hosts (default). Information is given only for adapters that are online (registered at the SCSI stack).
- -P, --ports
- List zfcp ports and FC remote ports.
- -b busid, --busid busid
- Show zfcp adapter, fc-host selected by busid.
- -l lun, --lun lun
- List zfcp unit(s) and SCSI device(s) selected by lun. (Information for several units might be shown if devices with equivalent LUNs are configured for different adapters or ports.)
- -p wwpn, --wwpn wwpn
- List zfcp port(s) and FC remote port(s) selected by wwpn. (Information for several ports might be shown if a remote port is configured for different adapters.)
- -V, --verbose
- Generate verbose output. Display sysfs path names of class and bus devices that are of interest for this object.
- -s, --sysfs /path/to/sys
- Use path as sysfs (for dbginfo archives).
- -h, --help
- Print help message and exit.
- -v, --version
- Display version info and exit.
NOTE¶
Options "-b", "-p" or "-l" are of restricting nature. They limit the output to those adapters, ports or units that match the specified busid, wwpn and lun. If none of the options "-H", "-P" and "-D" are specified, "-b" implies "-H", "-p" implies "-P" and "-l" implies "-D".EXAMPLES¶
- lszfcp -P -H -D -V
- Show all device paths of all zfcp adapters, ports, units and its associated SCSI devices, SCSI hosts, FC hosts and FC remote ports
- lszfcp -b 0.0.0815 -a
- Show all attributes of ccw_device, scsi_host and fc_host which belong to the adapter with busid "0.0.0815".
- lszfcp -D -b 0.0.0815 -p 0x5005123456789000 -l 0x0000000000000000
- Show the device which matches the given busid, wwpn and lun.
- lszfcp -b 0.0.0815 -p 0x5005123456789000 -l 0x0000000000000000
- Show all adapters that match the given busid, all ports that match the given busid and wwpnn and show all units that match the given busid, wwpn and lun.
- lszfcp -b 0.0.0815 -p 0x5005123456789000 -l 0x0000000000000000 -H -P -D
- Generates same output as previous example.
