7.7.8 EXPORT CELLDISK

Purpose

The EXPORT CELLDISK command prepares all cell disks or a specified cell disk before moving (importing) the cell disk to a different cell.

Syntax

EXPORT CELLDISK { ALL | cdisk_name }

Usage Notes

To move a cell disk from one cell to another, use the EXPORT CELLDISK and IMPORT CELLDISK commands. Usually, all disks are moved to a new cell if the current cell is failing. First, export the cell disk on one cell. Then, import the exported cell disk using the CellCLI utility on the cell where you moved the physical drive that contains the cell disk.

Using cell disk export and import does not preserve the security configuration details associated with ASM-scoped or DB-scoped security. Consequently, after a successful cell disk export and import, you must remove and reconfigure ASM-scoped or DB-scoped security.

When the EXPORT CELLDISK command is run:

• ALL exports all cell disks on the cells that have normal status.

• If the LUN associated with the cell disk is flagged as automatically-created, then that LUN is deleted as part of the export.

• A successfully exported cell disk has the status attribute set to ImportRequired, and the exported cell disk is displayed in the output of the LIST CELLDISK command.

• The following apply when a cell disk is exported (status='ImportRequired') before it is imported:

  • You can change the name and comment attributes.

  • You can drop the cell disk.

  • You cannot create a new grid disk on the cell disk.

• When a disk is exported, any writes from the disk controller cache to the disk are cleared, and the disk is flagged to indicate that the disk was exported. The grid disks on the disk are no longer visible to Oracle ASM. Any I/Os to the grid disks get errors.

Before exporting a cell disk, the data not synchronized with the grid disk (dirty data) must be flushed from flash cache to the grid disks. Not flushing dirty data may cause data loss.

Examples

The following example shows the EXPORT CELLDISK command.
