方法1： 在ASMCMD命令行中使用命令iostat查看
ASMCMD> iostat 5 Group_Name Dsk_Name Reads Writes DATA DATA_0000 7500588544 934144000 OCRVT OCRVT_0002 175992832 25706496 OCRVT _DROPPED_0001_OCRVT
read和write的单位都是bytes 方法2： 查看视图并手工计算
select group_number, disk_number, name, path, reads, writes, read_errs, write_errs, read_time, write_time, bytes_read, bytes_written; GROUP_NUMBER DISK_NUMBER NAME PATH READS WRITES READ_ERRS WRITE_ERRS READ_TIME WRITE_TIME BYTES_READ BYTES_WRITTEN ------------ ----------- ------------------------------ ------------------------------ ---------- ---------- ---------- ---------- ---------- ---------- ---------- ------------- 1 0 DATA_0000 /dev/asm-diskd 226655 66737 0 0 8051.29509 28851.5084 7524642304 939786240 2 1 _DROPPED_0001_OCRVT 2 2 OCRVT_0002 /dev/asm-diskc 6424 6307 0 0 626.637342 17695.4337 176164864 25866240
写入速度：BYTES_WRITTEN / WRITE_TIME 读取速递：BYTES_READ / READ_TIME
