Storage selection rules

■ Use only EMC LUNs that have their Room attribute set to the value Room1:

confineto eachof("VendorName"="EMC", "Room"="Room1")

■ Use only storage with VendorName set to the value of the variable

VENDOR_NAME, and with Room set to the value of the variable ROOM_NAME:

confineto eachof("VendorName"=VENDOR_NAME, "Room"=ROOM_NAME)

Note: VENDOR_NAME and ROOM_NAME are variables that are defined in a

capability. Their values are resolved when you enter values for the

capability during the creation of a VxVM object.

■ Create a volume using one or more LUNs from either or both of the

enclosures EMC1 and EMC2, and not from anywhere else:

confineto anyof("Enclosure"="EMC1", "Enclosure"="EMC2")

Note: When the anyof operator is used, ISP takes storage from the

operands in the order that they are specified. In this example, ISP first

attempts to select LUNs from the enclosure EMC1, and if this is not possible,

it selects LUNs from the enclosure EMC2. If this also is not possible, ISP

selects LUNs from both EMC1 and EMC2.

■ Use LUNs that originate either only from EMC or only from Hitachi:

confineto oneof("VendorName"="EMC", "VendorName"="Hitachi")

Note: When the oneof operator is used, ISP takes storage from the

operands in the order that they are specified. In this example, ISP first

attempts to select EMC LUNs, and if this is not possible, it selects Hitachi

LUNs.

■ Confine storage to be allocated from either Room1 or from Room2. If storage

is selected from Room1, Hitachi LUNs cannot be used. Similarly, if storage is

selected from Room2, EMC LUNs cannot be used.

confineto

oneof(eachof("Room"="Room1",noneof("VendorName"="Hitachi")), \

eachof("Room"="Room2", noneof("VendorName"="EMC")))

Note: In this example, ISP first attempts to select LUNs from Room1, and if

this is not possible, it selects LUNs from Room2.

■ Do not use LUNs from Room1 or LUNs from vendor EMC:

confineto noneof("VendorName"="EMC", "Room"="Room1")

Note: The noneof operator implies the logical union of its operands.
