Enhancements in HMC V7 R7.2.0

This package provides the following enhancements:

Command line
Added new commands for Hypervisor Active Memory Mirroring:
optmem -x -o start -t mirror -q –minutes
optmem -x -o stop
lsmemopt -m The following commands have been added to manage HMC password policies:
chpwdpolicy
Activates, disables, or modifies a password policy for the HMC
lspwdpolicy
Lists HMC password policy information
mkpwdpolicy
Creates a password policy for the HMC
rmpwdpolicy
Removes a password policy from the HMC
A new option, –trace, has been added to the chhmc command to provide Kerberos authentication logging to help debug Kerberos authentication failures. The chhmc command has been enhanced to support SLP service registration IP address configuration. The chhwres and lshwres commands have been enhanced to support Active Memory Mirroring for Hypervisor (POWER7 servers only). The following commands have also been added:
lsmemopt
Lists information, including status and progress information, about the most recent mirrored memory defragmentation operation that was started
optmem
Performs mirrored memory defragmentation operations
The chsyscfg and lssyscfg commands have been enhanced to support setting and displaying the TurboCore mode (some POWER7 servers only). The chhwres and lshwres commands have been enhanced to support setting and displaying the System Partition Processor Limit (SPPL), which is the maximum number of dedicated processors supported per partition (some POWER7 servers only). The following commands have been enhanced to support Quality of Service (QoS) priorities for virtual Ethernet adapters (POWER7 servers only): chsyscfg, lssyscfg, mksyscfg, chhwres, and lshwres. The following commands have been enhanced to support user specification of the MAC address for virtual Ethernet adapters (POWER7 servers only): chsyscfg, lssyscfg, mksyscfg, chhwres, and lshwres. The following commands have been enhanced to support controls on virtual Ethernet adapter and logical HEA MAC address overrides specified via the operating system (POWER7 servers only): chsyscfg, lssyscfg, mksyscfg, chhwres, and lshwres. The chhwres command has been enhanced to support dynamically changing the properties of a virtual Ethernet adapter which is assigned to a running partition (POWER7 servers only). The properties that can be changed are the IEEE 802.1Q setting, the virtual LANs, and the Quality of Service (QoS) priority. The lssyscfg -r lpar command has been enhanced to display RMC connection information. The chsysstate command has been enhanced to support network install for IBM i partitions (POWER7 servers only). A new option has been added to the updlic command to reboot the service processor. A new option has been added to the updlic command to perform hypervisor and partition firmware activation. The following commands have been added to support monitoring managed systems using SNMPv3 (POWER7 servers only):
chsvc
Changes the configuration of the SNMPv3 service on the HMC
lssvc
Lists the settings of the SNMPv3 service on the HMC
The following commands have been added to support virtual LAN (VLAN) statistics collection for managed systems (POWER7 servers only):
chstat
Changes the HMC settings for VLAN statistics collection
lsstat
Lists VLAN statistics collected for a managed system and the HMC settings for VLAN statistics collection
The chsyscfg command no longer supports setting the power on speed or power on speed override for POWER7 servers at the 7.2 firmware level or later. On POWER7 servers,the mksysplan command no longer gathers information from Virtual I/O Server (VIOS) partitions. General
Increased the JVM heap size and adjusted the thresholds used by the HMC monitors of memory usage. This enhancement reduces the number of E332FFFF error codes reported through call home. Dynamic System Partition Processor Limit Support gives the System Administrator a means to change the maximum number of dedicated processors supported per partition by changing the SPPL value. The Administrator will be allowed to change only the Next SPPL value , the current SPPL value will be populated with next SPPL on a system IPL by the FSP. It’s only available only on POWER7 795 platform. Added the ability to Enable/disable Turbocore for servers that support this feature from the HMC. System IPL is required for the new value to take effect. Enhanced SNMP support for HMC. Removed the existing fast/slow IPL options and replaced them with the autonomic IPL settings. CLI command support for i5/OS network install. CoD enhancements including support for larger processor minute values. Support dynamic edit of some virtual Ethernet properties such as supported VLANs. CLI support for enhanced password policies on the HMC. Active Memory Mirroring for Hypervisor: Supports PHYP memory mirroring. Allows the user to enable/disable PHYP memory mirroring on the system. An optimization tool for memory defragmentation is also included. Active Memory Mirroring for Hypervisor is an option which mirrors the main memory used by the firmware. With this option, an uncorrectable error resulting from failure of main memory used by system firmware will not cause a system-wide outage. HMC V7R7.2 introduces HMC controls and policies for MAC address assignment to partition virtual Ethernet and logical Host Ethernet adapters (LHEA). Using the HMC, you can optionally specify a custom MAC address for virtual Ethernet adapters assigned to a logical partition. You can also apply controls on virtual Ethernet and LHEA MAC address overrides specified at the operating system level. Provide QoS (Quality of Service) Support for virtual Ethernet adapters. Power Off Confirmation: A confirmation step has been added to the Power Off UI sequence. This step is presented when the Power Off task is selected and partitions are active within the system. IBM recommends that you first shut down partitions before powering off the managed system. However, you can choose to continue to power off the managed system. Additionally, if you attempt to Power Off the system but do not have access to all of the partitions in the system, then the Power Off task will not be allowed. You must have the “All Resources” access associated with your role to be able to power off the system. New Service Focal Point function New RV tasks added for tracking all MES results, and use of MES/WCII documentation for physical repair instructions in place of R&V panels for selected 9117 fru’s. New function has been added to Repair & Verify for Concurrent Maintenance Hardening. For MES procedures the CE is required to enter the MES number before starting an MES operation. New MES menu tasks on the HMC (Open MES, Close MES) display a dialog box to enter the MES number. The MES number is then used to record results of the MES operation and send data to IBM upon completion. Also for selected systems and FRUs, the CE is directed by R&V to use the hardcopy install/remove instructions provided as part of the MES documentation, instead of the traditional guided instruction panels displayed on the HMC by R&V. For the 720 release the systems and FRUs directing the CE to hardcopy instructions are:
9117-MMB (Feature Code 78C0-001): Concurrent MES for Memory Dimm add, GX Adapter add, and CEC enclosure add only. 9179-MHB (Feature Code 78C0-001): Concurrent MES for Memory Dimm add, GX Adapter add, and CEC enclosure add only. New Enterprise B2B VPN Inbound Connectivity Method.The B2B VPN offers some flexibilty to clients who cannot or do not wish to establish a remote support connection from the HMC to IBM for technical support purposes. Under special contract, you can choose to purchase a dedicated VPN connection between IBM and you company. With this option, IBM technical support can have access to your HMCs and also allow the HMC to accept incoming connections over the B2B VPN. To pursue this option, you should contact a business partner or an IBM marketing representative.
