使用NetAPP simulator:磁盘管理

Data ONTAP支持的磁盘类型包括FC-AL, ATA(PATA), SCSI, 支持的磁盘容量从4G到300G不等.

磁盘校验码格式有block checksum disks (BCDs)和zoned checksum disks (ZCDs)两种, 磁盘的校验码格式决定aggregate的校验码格式.

磁盘地址为如下格式
    HA.disk_id
其中HA指Host Adapter 编号, disk_id是该适配器上磁盘的编号, 对于FC-AL磁盘, 这一编号可以是0-128(Data ONTAP使用16-127), 对于scsi磁盘这一编号是0到15.

RAID组中的磁盘类型包括
    Data Disk
    Hot Spare Disk
    Parity Disk
    Double-Parity Disk

查看当前系统连接的磁盘可以用storage show disk -x

netapp> storage show disk -x

storage show disk -a可以查看到更详细的信息.
storage show disk -p可以查看磁盘多路径的信息

查看当前磁盘连接到ha的信息可以使用fcadmin device_map

df可以用来查看磁盘使用情况

netapp> df

删除磁盘上的数据可以使用disk sanitize命令

netapp> disk sanitize start v4.28
Warning : The sanitization process involves a disk format and writing repeated patterns. This process can take a long time. Are you sure? yes
