vxdmpadm iostat
This command displays the I/O statistics for a single disk, all disks in an array, or all the disks of all the arrays in the host. You can group the statistics by device or array. If no groupby is specified, then statistics is shown for all the paths. The statistics can be set to display after a specified number of seconds and for a specified number of times through this CLI option.
vxdmpadm iostat vxdmpadm [-g<DynamicDiskGroupName>] iostat [showdevice|showarray] [interval=#] [count=#] <DiskName> | p#c#t#l#> vxdmpadm [-g<DynamicDiskGroupName>] iostat [showdevice | showarray | showall] [groupby=<device | array>] [-u <KB | MB | GB>] [interval=seconds] [count=N] [<diskname | p#c#t#l#>]
The following attributes apply:
showdevice|showarray | Display I/O statistics:
|
showall | Displays the I/O statistics for all the paths of all the arrays that are connected to the host. Diskname should not be specified with this option. |
groupby=device | The I/O statistics is shown per device. If no groupby is specified, then statistics is shown for all devices. |
groupby=array | The I/O statistics is shown per array |
KB | Data that is read or written is shown in KiloBytes/Second |
MB | Data that is read or written is shown in MegaBytes/Second |
GB | Data that is read or written is shown in GigaBytes/Second |
interval=# | # specifies the amount of time (seconds) between displays of the I/O statistics. (Default value is 5 seconds between displays.) |
count=# | # specifies the number of times the I/O statistics are displayed. (Default is infinite number of displays.) |
<DiskName> | The designated disk, which can be specified by the device name (such as Harddisk2) or the internal disk name (such as Disk2). The -g option must precede the internal disk name (for example, -gDG2 Disk1). |
p#c#t#l# | The #s correspond to the port, channel, target, and LUN of a disk. |
