Configuring a Virtual Disk
Virtual disk configuration tasks include:
• “Adding a Virtual Disk” (page 147)
• “Troubleshooting Problems With Adding a Virtual Disk” (page 148)
• “Altering Virtual Disk Attribute Values” (page 149)
• “Deleting a Virtual Disk” (page 150)
Adding a Virtual Disk
The “ADD DISK Command” (page 194) adds a virtual disk to the system configuration database.
Considerations for ADD DISK and Virtual Disks
Before adding a virtual disk verify that:
• The TMF product is running on the system.
• These objects are in the STARTED state:
The physical disk volume used as a catalog by the SMF master process◦
◦ The SMF master process ($ZSMS)
◦ The storage pool process to be specified in the POOL attribute
◦ The disk volume where the CATALOGLOCATION for the storage pool process resides
