Information in this document applies to any platform.
The "asmcmd help iostat" command reports that Read_Time and Write_Time are in hundredths of a second in the Oracle Automatic Storage Management Administrator's Guide 11g Release 2 (11.2), Chapter ASMCMD Disk Group Management Commands, Table 12-32 Attribute descriptions for iostat command output.
However, if you look at the V$ASM_DISK_STAT view it states the results are in seconds for the READ_TIME and WRITE_TIME.
They both show the same value when used on an 220.127.116.11 Oracle Database. Which one is correct?
