exclude
An exclude rule omits a set of LUNs from being allocated to a VxVM object.
Expressions involving exclude can only use the allof and eachof operators to
combine multiple arguments. By default, ISP applies the allof operator.
See “Storage selection rule operators” on page 159.
The following examples demonstrate the application of exclude rules:
■ The following examples that demonstrate rules which prevent storage being
assigned from EMC or Hitachi disks, are equivalent:
exclude "VendorName"="EMC", "VendorName"="Hitachi"
exclude allof("VendorName"="EMC", "VendorName"="Hitachi")
■ The following example does not use EMC LUNs from Room1:
exclude eachof("VendorName"="EMC", "Room"="Room1")
■ The following example does not use disks with VendorName set to the value of
the variable VENDOR_NAME:
exclude "VendorName"=VENDOR_NAME
VENDOR_NAME is a variable that is defined in a capability. Its value is resolved
when the VxVM object is created.
■ The following example excludes certain LUNs from the enclosure Enclr1:
exclude allof("DeviceName"="Enclr1_1", "DeviceName"="Enclr1_2")
multipath
A multipath rule specifies how tolerant a VxVM object is to the failure of a number
of specified components. The rule defines how many paths a VxVM object should
have available through each component.
The multipath rule does not take any rule operators.
The following examples demonstrate the application of multipath rules:
■ The following example tolerates the failure of one controller:
multipath 2 "Controller"
