Deporting of a disk group

Deporting of a disk group

What is a deported disk group?

• The disk group and its volumes are unavailable.
• The disk cannot be removed
• The disk group cannot be accessed until it is imported

Before deporting a disk group:

• Unmount file systems
• Stop Volumes

When you deport a disk group, you can specify:

• A new host
• A new disk group name

vxdiskadm:

“Remove access to (deport) a disk group”

vxdg deport

Before Deporting:

# vxdisk list

DEVICE       TYPE            DISK         GROUP        STATUS

IBM_VSCSI0_1 auto:LVM        -            -            LVM

TagmaStore-USP1_0 auto:cdsdisk    disk03       markdg       online

# vxdg deport markdg

# vxdisk list

DEVICE       TYPE            DISK         GROUP        STATUS
