switch and router. The value should be in
the vendors' documentation. Set the
CONFIGURED_IO_TIMEOUT_EXTENSION
to the sum of the values for the switches and
routers. If there is more than one possible
path between the NFS server and the cluster
nodes, sum the values for each path and use
the largest number.
CAUTION: Serviceguard supports
NFS-mounted file systems only over
switches and routers that support MBTD. If
you are using NFS-mounted file systems,
you must set
CONFIGURED_IO_TIMEOUT_EXTENSION
as described here.
For a fuller discussion of MBTD, see the
white paper Support for NFS as a file system
type with Serviceguard 11.20 on HP-UX 11i v3
which you can find at www.hp.com/go/
hpux-serviceguard-docs.
• For clusters in which both of the above
conditions apply.
In this case, set the
CONFIGURED_IO_TIMEOUT_EXTENSION
to the higher of the two values you get from
following the instructions in the preceding
two bullets.
Default is 0.
