This should work if you add a resource of type SUNW.gds to the resource group. Create a shell script which checks for acceptable scan rates. Let the script return 0, if scan rate is ok and 1 otherwise. Then set this script as Probe_command of the resource. If scan rate is too high, the resource will "fail" and trigger a cluster switch of the resource group.
We don't have any running solaris cluster here any more, so I cannot verify this procedure. You should try it on a test machine first.

Hi Guys,
The management is being frisky about scan rate in the range of a few thousands ( 4 digit scan rates occasionally). After much research ive concluded that its ok to have high scan rates , unless it leads to swapping/ it falls above 1:4 ratio with free rate (fr:sr)

scha_resourcetype_get
scha_resourcetype_get(1HA) Sun Cluster Commands scha_resourcetype_get(1HA)
NAME
scha_resourcetype_get - access resource type information
SYNOPSIS
scha_resourcetype_get -O optag -T type
DESCRIPTION
The scha_resourcetype_get command accesses information about a resource type that is registered with the Resource Group Manager (RGM).
Use this command in shell script implementations of the callback methods for resource types that represent services that are controlled by
the RGM. This command provides the same information as the scha_resourcetype_get(3HA) C function.
Information is output by this command to the standard output (stdout) in formatted strings, as described in the scha_cmds(1HA) man page.
Output is a string or several strings that are output on separate lines. You can store the output in shell variables. You can also parse
the output by using the awk(1) command or other shell commands for further use by the script.
You need solaris.cluster.resource.read RBAC authorization to use this command. See the rbac(5) man page.
Authorized users can issue privileged Sun Cluster commands on the command line from the pfsh(1), pfcsh(1), or pfksh(1) profile shell. A
profile shell is a special kind of shell that enables you to access privileged Sun Cluster commands that are assigned to the Sun Cluster
Commands rights profile. A profile shell is launched when you run su(1M) to assume a role. You can also use pfexec(1) to issue privileged
Sun Cluster commands.
OPTIONS
The following options are supported:
-O optag Indicates the information to be accessed.
Note -
optag options, such as API_VERSION and BOOT, are not case sensitive. You can use any combination of uppercase and lowercase
letters when you specify optag options.
The following optag values retrieve the corresponding resource type properties. The value of the named property of the
resource's type is output.
