Planning Volume 2, Control Workstation and Software Environment
In addition to the restrictions on switch traffic, as illustrated in
Example 1, data cannot generally be shared across system partitions.
- Access to PSSP virtual shared disks and pseudo-tape devices across system
partitions is not supported.
- Twin-tailed disks cannot span system partitions.
- A physical file system, that is, the logical volumes containing the files,
cannot span system partitions.
- You can use a distributed file system to mount file systems across
partition boundaries, just as you would use a distributed file system from one
SP to another. Keep in mind that doing this might effect nodes in both
partitions in terms of both compute and network utilization.
