lszfcp (v1.5.2/3) Script to show information contained in sysfs about zfcp adapters, ports and units that are online; from zconf.
mon_statd (v1.5.6) Starts Linux-z/VM monitoring daemons.
osasnmpd (v1.1.0) UCD-SNMP/NET-SNMP subagent implementing MIBs provided by OSA-Express features Fast Ethernet, Gigabit Ethernet, High Speed Token Ring and ATM Ethernet LAN Emulation in QDIO mode.
Note: You need at least the UCD-SNMP 4.2.3 package installed, before building the osasnmpd subagent.
For more information on UCD-SNMP/NET-SNMP refer to: http://net-snmp.sourceforge.net/
qetharp (v1.1.0) Read and flush the ARP cache on OSA Express network cards.
qethconf (v1.2.0) bash shell script simplifying the usage of qeth IPA (IP address takeover), VIPA (Virtual IP address) and Proxy ARP.
qethqoat (v1.18.0) Query the OSA address table (OAT) and display physical and logical device information
scsi_logging_level (v1.5.2/3) Create, get or set the logging level for the SCSI logging facility.

tape390_crypt (v1.5.6) Control and query crypto settings for 3592 tape devices.
tape390_display (v1.1.0) Display information on the message display facility of a tape device.
ttyrun (v1.9.0) The ttyrun tool safely starts getty programs and prevents respawns through the init program, if a terminal is not available.
tunedasd (v1.3.0) Adjust tunable parameters on DASD devices.
vmconvert (v1.3.2) Convert system dumps created by the z/VM VMDUMP command into dumps with LKCD format.
These LKCD dumps can then be analyzed with the dump analysis tools lcrash or crash.
vmcp (v1.5.0) Allows Linux users to send commands to the z/VM control program (CP). The normal usage is to invoke vmcp with the command you want to execute. The response of z/VM is written to the standard output.
vmur (v1.6.2) Allows to work with z/VM spool file queues (reader, punch, printer).
[zconf] Set of scripts to configure and list status information of Linux on System z devices.
zdsfs (v1.24.0) Use the zdsfs command to mount a z/OS DASD as Linux file system.
zfcpdbf (v1.5.0) Display debug data of zfcp. zfcp provides traces via the s390 debug feature. Those traces are filtered with the zfcpdbf script, i.e. merge several traces, make it more readable etc.
zfcpdump (v1.2.0) Dump tool to create system dumps on fibre channel attached SCSI disks. It is installed using the zipl command.
zfcpdump v2 is the second version of the zfcpdump tool which was first integrated into upstream kernel 2.6.23.
zgetdump (v1.0.0) Retrieve system dumps from either tapes or DASDs.
ziomon tools (v1.8.0) Set of tools to collect data for zfcp performance analysis.
Report utilities (ziorep_config, ziorep_traffic, ziorep_utilization) for performance data report generation.
