Important ASM Commands and Concepts

Rebalancing Disks

When you drop/remove a disk from the diskgroup, it is important to apply the proper value for the power setting for rebalance and to use the WAIT command.

Example ASM Command:

SQL> ALTER DISKGROUP <DiskGroupName> DROP DISK <diskName> REBALANCE POWER 8 WAIT;

The rebalance command moves the data off of the disk that you are removing from the diskgroup, distributing the data across the remaining DISKS.
The power setting is a number from 1 to 11. It determines how much processing power is dedicated to the rebalance, versus normal operations. Unless the encrypting occurs during heavy traffic volume, the minimum value you should use is 6. Otherwise, consult the customer’s DBA for the proper setting. An appropriate value to start with is 8.

Mapping Raw Devices

You can map raw devices for this configuration using:

EMC PowerPath

If using EMC PowerPath then the device names are similar to the following: /dev/hdiskpowerXX.

When browsing the CipherTrust Manager through the local host, you cannot find Power Path devices. You must manually input the paths. The guarded disk names are prepended with: /dev/secvm.

Checking Rebalance Status

The wait command is very important when ASM performs a rebalance. When you specify wait, the command prompt does not display until all of the data is rebalanced and migrated off of the disk. If you do not specify wait, the command prompt returns immediately, and you must issue the following ASM command to check the status of the rebalance:

SQL> select * from v$asm_operation;

This command returns information about the:

State
Current power level
Current amount rebalanced
Estimated work until completion
Rate
Estimated minutes
Any error codes

Note

It is highly recommended that you always specify the wait command when performing a Drop Disk with Rebalance. If it is not specified, ASM may prematurely release the disk, thereby allowing CTE to place a GuardPoint on the disk before the rebalance completes. This action may corrupt the data.

Oracle cautions against this issue:

Caution

The ALTER DISKGROUP...DROP DISK statement returns before the drop and rebalance operations complete. Do not reuse, remove, or disconnect the dropped disk until the HEADER_STATUS column in the V$ASM_DISK view for this disk changes to FORMER. You can query the V$ASM_OPERATION view to determine the amount of time remaining for the drop/rebalance operation to complete. For more information, refer to the *Oracle Database SQL Language Reference and the Oracle Database Reference.
