asmcmd之卷管理

ASMCMD Volume Management Commands(卷管理),通过ADVM Volume,我们可以建立ACFS文件系统,ACFS文件系统功能也能强大。卷管理涉及的命令有:volcreate, voldelete, voldisable, volenable, volinfo, volresize, volset, volstat
    
ACFS
Oracle Automatic Storage Management Cluster File System (Oracle ACFS) is a multi-platform, scalable file system, and storage management technology that extends Oracle Automatic Storage Management (Oracle ASM) functionality to support customer files maintained outside of Oracle Database. Oracle ACFS supports many database and application files, including executables, database trace files, database alert logs, application reports, BFILEs, and configuration files. Other supported files are video, audio, text, images, engineering drawings, and other general-purpose application file data.    
    
volcreate   创建Volume,volume是在Diskgroup上创建
Creates an Oracle ADVM volume in the specified disk group.
        volcreate -G diskgroup -s size [ --column number ] [ --width stripe_width ] [--redundancy {high|mirror|unprotected} ] [--primary {hot|cold}] [--secondary {hot|cold}] volume
        The options for the volcreate command are described below.

        -G diskgroup            - Name of the disk group containing the volume.
        -s size                 - Size of the volume to be created in units
                                  of K, M, G, or T. The unit designation must
                                  be appended to the number specified.
                                  No space is allowed. For example: 20G
        --column number         - Number of columns in a stripe set.
                                  Values range from 1 to 8. The default
                                  value is 4.
        --width stripe          - Stripe width of a volume. The value
                                  can range from 4 KB to 1 MB, at
                                  power-of-two intervals, with a default
                                  of 128 KB.
        --redundancy {high|mirror|unprotected}  - Redundancy of the
                                  Oracle ADVM volume which can be
                                  specified for normal redundancy disk
                                  groups. The range of values are as follows:
                                  unprotected for non-mirrored redundancy,
                                  mirror for double-mirrored redundancy, or
                                  high for triple-mirrored redundancy.
                                  If redundancy is not specified, the
                                  setting defaults to the redundancy level
                                  of the disk group.
        --primary {hot|cold}    - Intelligent Data Placement specification
                                  for primary extents, either hot or cold region.
        --secondary {hot|cold}  - Intelligent Data Placement specification
                                  for secondary extents, either hot or cold
                                  region.
        volume                  - Name of the volume to be created. Can be
                                  a maximum of 11 alphanumeric characters;
                                  dashes are not allowed. The first character
                                   must be alphabetic.
