Advanced parameters and detailed application notes for the VSphere HA 5.x series

• DAS.ALLOWNETWORKX-Allows specific management networks to be specified for vsphere ha's heartbeat network, x can be Arabic numerals 0-9. This option is not valid when the Vsan function is activated in 5.5.

• Das.ignoreredundantnetwarning-If ESXi host under vsphere Ha management does not have redundant networks, it will be alerted, so you can skip the alert with this parameter;

• Das.heartbeatdsperhost-vsphere ha defaults to configure 2 heartbeat Datastore per ESXi host, which can help specify the number of heartbeat storage for the host, which can be up to 5;

• Das.ignoreinsufficienthbdatastore-This option is used to skip this warning detection when the number of heartbeat storage for ESXI host is insufficient, and the value can be true;

• Das.includeftcompliancechecks-This option is used to detect whether the cluster configuration meets the requirements of fault tolerance, and if this option is false, it is not detected;

• DAS.VMMEMORYMINMB-This option indicates the minimum reserved value of the virtual machine when the reserved memory of the virtual machine is 0 o'clock, in megabytes;

• Das.vmcpuminmhz-This option is the minimum reserved value of the virtual machine when the virtual machine's CPU is reserved, in MHz, the default is 32;

• Das.slotcpuinmhz-This option represents the maximum number of CPU portions in the slot size, with a parameter of MHz;

• DAS.SLOTMEMINMB-This option represents the maximum number of CPU parts in the slot size, with the parameter MB;

• Das.maxvmrestartcount-This option indicates how many times the FDM master host tries to restart the virtual machine on the HA applaud host, this value is not recommended to set too large, and, It is usually used in conjunction with Das.maxvmrestartperiod, that is, the number of restart virtual machine attempts within a limited time. However, the secondary VM generated for FT needs to be solved by this parameter to solve the Das.maxftvmrestartcount parameter;

• Das.maxvmrestartperiod-This parameter is used to limit the time that FDM master attempts to restart the VM, longer than the attempt, in seconds, which is usually used in conjunction with Das.maxvmrestartcount;

• Das.maskcleanshutdownenabled-When the virtual machine and its datastore are unreachable, HA cannot detect whether the virtual machines have been restarted successfully, in which case activating this option is equivalent to telling FDM Master host this virtual machine needs to be restarted, at this point, the FDM Master host will perform a reboot attempt, if this value is False then FDM Master will ignore the problem, pretending that the VM does not need to restart;

• Das.respectvmvmantiaffinityrules-Attempts to restart the virtual timings after an HA failure is attempted, clarifying the affinity rule between VMs and VMS, which defaults to false and can be adjusted to true;

• DAS.ISOLATIONADDRESSX-This is the isolation response address, default is the default gateway, but the user can according to their own needs up to 0-9, total 10 isolation response address, to resolve the redundant isolation response address problem. In Vsphere 5.5, if the Vmkernel interface type of Vsan is enabled, this address is also used as an internal isolation response detection;

• Das.usedefaultisolationaddress-This option is usually used with DAS.ISOLATIONADDRESSX, which is set to False when DAS.ISOLATIONADDRESSX is required;

• Das.config.fdm.isolationPolicyDelaySec-the time interval at which this UXANXIANGZESHIFDM agent waits to execute an isolation response policy, with a minimum of 30 seconds, That is: the detection of the host is quarantined for a long time before performing the isolation response action;

• Das.isolationshutdowntimeout-This parameter is how long FDM waits for the virtual machine to perform the power off action after shutdown guest, and if not set, the default is 300 seconds;

• DAS.IOSTATSINTERVAL-FDM detects the presence of a virtual machine's heartbeat and triggers a virtual machine or application monitoring policy when the heartbeat disappears. FDM checks if there is an I/O occurrence within the iostatsinterval time, and if not, triggers a virtual machine reset instruction, which defaults to 120 seconds;

• Das.maxftvmsperhost-This parameter indicates the maximum number of VMS on each ESXi host to open ft, and if not set, the default is 4, or 1 or 0, which means that the limit on how many VMs to turn on FT is turned off;

• Das.config.log.maxFileNum-This parameter controls the number of FDM log files;

• Das.config.log.maxFileSize-This option indicates that the maximum value of the FDM log file is set, usually the 1MB size;

• Vpxd.dads.aamMemoryLimit-This option represents the memory limit of the AAM resource pool, typically 100MB, which acts on all cluster under vcenter Server inventory;

• Vpxd.das.electionwaittimesec-vcenter server waits for the host election time interval is how much, if not set is 120 seconds, this option is mainly used for slave between the host election time range control;

• Fdm.nodegoodness-When the master election is executed, this goodness value is exchanged between the FDM agent, and then the host with the larger goodness value becomes the new master host. Of course, the host's moid priority is greater than this goodness parameter. If you want to forcibly designate an ESXi host as the master host, you can set this value a bit larger, which does not work at the cluster level, but instead, it acts on the host level;

• VPXD.DAS.SENDPROTECTLISTINTERVALSEC-This option indicates the minimum time interval that vcenter server sends the protected list to the master host and, if not set, the default is 60 seconds The setting of this option can control how often the master host gets VM changes to the vcenter server;

• Fdm.cluster.vsanDatastoreLockDelpy-Represents the delay before the Vsan Datastore object acquired. Virtual machine failover is not performed on Datastore after the Vsan datastore is master acquired. This value defaults to 30 seconds;

• Vpxd.das.slotmemminmb-vcenter Server sets the global virtual machine reservation value, the preceding DAS.SLOTMEMMINMB will overwrite this value;

• Vpxd.das.slotcpuminmhz-vcenter Server sets the global virtual machine reservation value, the preceding Das.slotcpuminmhz will overwrite this value;

• Das.config.fdm.hostTimeout-Control FDM host to wait for the FDM agent on the slave host corresponding time, if not set, the default is 10s;

• Fdm.deadicmppinginterval-When FDM is unable to communicate with the master host, check that the slave host's network is up to the ICMP ping interval, which defaults to 10 seconds;

• Das.config.fdm.icmpPingTimeout-Defines the time-out period for FDM to wait for ICMP ping feedback and, if not set, defaults to 5s;

• Vpxd.das.heartbeatPanicMaxTimeout-This option is waiting for the host Psod state of the length of time, the default is 60s, after the timeout, will restart the virtual machine;

• Das.config.fdm.policy.unknowStateMonitorPeriod-Defines the time that the Ha Master agent waits to detect a virtual machine failure, which defaults to 10s;

• Das.perhostconcurrentfailoverslimit-Represents the number of concurrent virtual machines failover, default is 32;

• Das.config.fdm.ft.cleanupTimeout-This parameter indicates detection for the FT virtual machine, which defaults to 900 seconds;

• Das.config.log.outputToFiles-Indicates the output of FDM log files;

• Das.config.log.directory-Represents the specified FDM log file directory, which can be in/VAR/LOG/VMWARE/VDM format;

• Das.config.fdm.stateLogInterval-Indicates the generation frequency of the FDM log, which defaults to 600 seconds;

• Das.config.fdm.event.maxMasterEvents-Defines the maximum number of event caches for the master host, which defaults to 1000;

• Das.config.fdm.event.maxSlaveEvents-Defines the maximum number of event caches for the slave host, which defaults to 600;

• Vpxd.das.reportNoMasterSec-Indicates how long vcenter server detects that it has not received the status of FDM agent feedback on the master host, which defaults to 120 seconds
