ensures that the mounts occur in the correct order. (Local mounts

occur after boot NFS mounts but before other NFS and automounter

mounts).

Question: How do I conﬁgure local swap on clients?

Answer: Run SAM on each client that will have local swap and use the “Disk

Devices” subarea under “Disks and Filesystems” to add a local disk

for swap.

• If you choose to add this device swap as primary swap, SAM will

build a new kernel and reboot the client.

You may want to remove the NFS swap (swapfs) entry from

/etc/fstab.

• If you choose not to add the device swap as primary swap, the system

will use the NFS swap entry during the initial part of the boot

process and then use the device swap (it will usually be priority 1

which is higher than the NFS swap at priority 5).

Cluster-wide Tasks

Question: Is a resource considered to be a cluster-wide resource if it has been added

to every system in a cluster via separate “Add” tasks (that is, the “Manage

Cluster-Wide” option was not used)?

Answer: No, adding a resource to each system in a cluster one at a time does not

create a cluster-wide resource.

Even though the result is the same as if you had done a cluster-wide

task, SAM cannot know with certainty that you want the resource

treated as a cluster-wide resource. But you can still use the “Manage

Cluster-Wide” action to let SAM know that you want to manage the

resource cluster-wide from now on.

Question: If a cluster-wide resource is removed from a system, how can it be added

back later?
