Managing Shared Disks

Chapter 6. Managing and monitoring Virtual Shared Disks

This chapter tells you how to do the following tasks:

• Control the IBM Recoverable Virtual Shared Disk subsystem.
• Change the states of virtual shared disks (do only when you do not have the IBM Recoverable Virtual Shared Disk subsystem operating.)
• Monitor virtual shared disks.
• Dynamically refresh the IBM Recoverable Virtual Shared Disk subsystem after changing an existing virtual shared disk configuration.
• Make changes to twin-tailed volume groups.
• Set up new physical disks.
• Recable without adding new physical disks.
• Converting twin-tailed virtual shared disks to concurrent virtual shared disks.
• Run virtual shared disk diagnostics.
• Collect information for problem determination.
