InfoScale™ 9.0 Cluster Server Bundled Agents Reference Guide - Solaris

CacheObjectName

Specifies the cache object name; it can be a mount point or disk group/volume.

Type and dimension: string-scalar

CacheArea

Specifies the name of the cache areas.

The writeback cache area is valid only when CacheMode = writeback and if it is a VxFS cache area.

Type and dimension: string-association

Example:

CacheArea @sys1 = { Read = sfcachearea_11, Writeback = sfcachearea_12 }

CacheArea @sys2 = { Read = sfcachearea_21, Writeback = sfcachearea_22 }

CacheMode

Specifies the caching mode. Following are the caching modes:

Type and dimension: string-scalar

Default: read

CacheFaultPolicy

Specifies the action to be performed in case of a cache fault. Following are the values:

Type and dimension: string-scalar

Default: IGNORE

FaultOnMonitorTimeouts

Defines whether VCS interprets the Monitor timeout as a resource fault. By default, the FaultOnMonitorTimeouts attribute is set to 4, but the SFCache agent overrides this value and sets it to 0.

The Monitor function must timeout four times in a row before the resource is marked as faulted. The first monitor timeout timer and the counter of timeouts are reset after one hour of the first monitor timeout.

If the attribute is set to 0, VCS does not treat Monitor timeout as a resource fault. If the attribute is set to 1, VCS interprets the Monitor timeout as a resource fault and the agent calls the Clean function to shutdown the resource.

Default: 0

NumThreads

Number of threads that are used within the agent process for managing resources. This number does not include the number of threads that are used for other internal purposes. Setting the NumThreads attribute to a higher value may decrease the time required to go online or the time required to monitor a large number of SFCache resources.

Type and dimension: static integer-scalar

Default: 1
