This book describes the shared disk management facilities of the Scalable POWERparallel Systems (SP) -- the IBM Virtual Shared Disk, Hashed Shared Disk, and Recoverable Virtual Shared Disk optional components of the IBM Parallel System Support Programs for AIX (PSSP) program product. These components help you manage your SP's disks so you can let multiple nodes share the information they hold. The book includes an overview of the components and explains how to plan for them, install them, and use them to add reliability to your data storage.
For a list of related books and information about accessing online information, see the bibliography in the back of the book.
This book applies to the planning for, migration to, installation, and use of the optional shared disk management components of PSSP Version 3 Release 4. To find out what version of PSSP is running on your control workstation (node 0), enter the following:
splst_versions -t -n0
In response, the system displays something similar to:
0 PSSP-3.4
If the response indicates PSSP-3.4, this book applies to the version of PSSP that is running on your system.
To find out what version of PSSP is running on the nodes of your system, enter the following from your control workstation:
splst_versions -t -G
In response, the system displays something similar to:
1 PSSP-3.4 2 PSSP-3.2 7 PSSP-3.1.1 8 PSSP-2.4
If the response for a particular node indicates PSSP-3.4, this book applies to the version of PSSP that is running on that node.
If you are running mixed levels of PSSP, be sure to maintain and refer to the appropriate documentation for whatever versions of PSSP you are running.
