In Red Hat Enterprise Linux 5.4, the s390utils package has been rebased to version 1.8.1. For a full list of features that this rebase provides, please refer to the Package Updates section of the Technical Notes
In Red Hat Enterprise Linux 5.4, the s390utils package has been re-based to version 1.8.1. This new version includes such features as:
- Shutdown Action Tools
This feature provides tools to configure a (one-time) shutdown action via the
command line, allowing for easy one-time shutdown actions without having to edit configuration files or sysfs.
The new Shutdown Action Tools are: chreipl, chshut, lsreipl, lsshut
- DS8000 Disk Encryption
This item allows the customer, without having to ask the Storage administrator
if the physical disks where his data is being stored are encrypted or not.
- Shutdown actions interface (userspace tools)
Update to dumpconf, part of s390-tools, to support Shutdown actions interface (kernel). This features improves the flexibility of VMCMD, which was before restricted to
This update allows to introduce up to 5 VM commands. For example:
VMCMD_1='MSG * Starting VMDUMP'
- Large image dump on DASD
Newer hardware systems allow many terabytes of main memory, which is unable to previously be dumped to DASD. This feature proves new options for zipl and zgetdump to generate read and multi-volume dumps, eliminating restrictions on main memory.
- Added vmconvert option to vmur tool
This feature modifies the vmur tool to automatically convert vmdumps when requested. This is implemented by adding an option to the vmur tool, that when set, inteprets dat read from the vm reader and converts that dump immediately using vmconvert. This feature provides a simpler method for access to problem analysis data, which results in faster problem determination.
- FCP Performance Data Collection & Analysis (userspace)
This item will make possible to have a better understanding of the SCSi activities and performance of end systems, being able afterward to better solve FCP issues regarding SCSI workloads.
- TTY Terminal Server over IUCV (userspace)
This implements client & server for a TTY terminal server under z/VM using IUCV as the communication vehicle. This is accomplished by implementing a terminal server running on a dedicated z/VM guest. The terminal server accepts connections via the normal network and uses the AF_IUCV socket API to provide console session access to Red Hat Enterprise Linux guests.
The TTY over IUCV was implemented to solve concurrent access contention to the Linux console for many Linux Administrators, who frequently find the z/VM 3270 interface inadequate.
