of four capacities per cluster, unless you use the reserved

 

CAPACITY_NAME package_limit; in that case, you can

 

use only that capacity throughout the cluster.

 

For all capacities other than package_limit, the default

 

weight for all packages is zero, though you can specify a

 

different default weight for any capacity other than

 

package_limit; see the entry for WEIGHT_NAME and

 

WEIGHT_DEFAULT later in this list.

 

See “About Package Weights” (page 144) for more

 

information.

 

Can be changed while the cluster is running; will trigger a

 

warning if the change would cause a running package to

 

fail.

MEMBER_TIMEOUT

The amount of time, in microseconds, after which

 

Serviceguard declares that the node has failed and begins

 

re-forming the cluster without this node.

 

Default value: 14 seconds (14,000,000 microseconds).

 

This value leads to a failover time of between approximately

 

18 and 22 seconds, if you are using a Quorum Server, or

 

a Fiber Channel cluster lock, or no cluster lock. Increasing

 

the value to 25 seconds increases the failover time to

 

between approximately 29 and 39 seconds. The time will

 

increase by between 5 and 13 seconds if you are you using

 

a SCSI cluster lock or dual Fibre Channel cluster lock).

 

Maximum supported value: 300 seconds (300,000,000

 

microseconds).

 

If you enter a value greater than 60 seconds (60,000,000

 

microseconds), cmcheckconf and cmapplyconf will note

 

the fact, as confirmation that you intend to use a large value.

 

Minimum supported values:

 

3 seconds for a cluster with more than one heartbeat

 

subnet.

 

8 seconds for a cluster with more than one heartbeat

 

using CFS (see “Creating a Storage Infrastructure with

 

Veritas Cluster File System (CFS)” (page 199) for more

 

information about CFS; see also the “Considerations

 

for CVM” under HEARTBEAT_IP earlier in this section).

 

14 seconds for a cluster that has only one Ethernet

 

heartbeat LAN

 

22 seconds for a cluster that has only one IP over

 

Infiniband (IPoIP) heartbeat LAN
