Allow SSI connection between z/VM systems using Hipersockets (direct and bridged)

Requiring physical CTC connections for an SSI cluster within a single physical CEC incurs some cost for additional hardware (e.g. preferably 2 FICON cards for SPOF avoidance). Modifying ISFC communication to optionally use Hipersockets would allow...

GDPS z/VM online/offline volumes hindering an ENABLED HYPERSWAP status

We have a GDPS environment with z/OS and z/VM and we are testing such that we have both participating in HYPERSWAP. The z/VM has a list of volumes for z/VM's use and those volumes are known to both z/OS and z/VM but z/OS volumes are only ever brou...

Add flash memory to z/VM paging

The idea is to enable z / VM to use the flash memory as paging area system instead of dasd disks to increase agility.

Displaying configured cipher suites in configured order under SYSTEM DTCPARMS.

Specifying a preferred order of cipher suites under SYSTEM DTCPARMS is not the exact order that is displayed from z/VM systems. The 'ssla q status details' command list an order that is not configured. Even presenting the cipher suites order to ne...

Query Tapes Details update

Huge HW configurations (or not) impose to be accurate on all the installed materials. IODF or HMC have in most cases a very restricted access. Quick access to configuration informations by a Query could make the control, verifications, and other t...

Improve LDAPSRCH performance in z/VM

We use LDAPSRCH to query our enterprise identity management system from z/VM applications to gather required information. The z/VM version LDAPSRCH is extremely slow, taking around 3 seconds for a simple query. The identical query runs <.5 seco...

z/VM TCPIP utilities (PING FTP TELNET TRACERTE) use the first address returned from a DNS server. This may be an IPV6 address - if the originating system is only IPV4 the result is "EDC8118I Network is unreachable". This can be bypassed by using the ADDRTYPE arg but we would prefer smarter DNS lookup. z/OS and zLinux handle this without using ADDRTYPE.

See "Your idea".

Install correct USER DIRECT when selecting non-SSI install

When installing zVM 7.3 we chose the option non-SSI install, but the USER DIRECT that was included is in the format of SSI/SSI Ready. This means that when companies grow their system beyond the very limited 8 nodes of SSI they will have to manuall...

RVARY password reply handling should be changed

When issuing RVARYPW (reply after having issued rvary command) it is displayed in clear text in operator's console log. This is a big difference to z/OS reply handling and should be changed in z/VM. The input to this reply should be hidden to avoi...
