SANtricity 11.8 Commands ( CA08871-194 ～ 196 )
Show drive performance statistics
The show allDrives performanceStats command returns information about drive performance.
Supported Series
This command applies to any individual storage system, including the HB2100/HB2200/HB2300, HB5100/HB5200, AB6100 and AB3100 series, as long as all SMcli packages are installed.
Roles
To execute this command on an HB2100/HB2200/HB2300, HB5100/HB5200, AB6100, or AB3100 storage system, you must have the Storage Admin role.
Context
For each drive in the storage system, this command returns the following information:
-
The storage system containing the drive or drives
-
The current I/O latency
-
The maximum I/O latency
-
The minimum I/O latency
-
The average I/O latency
Syntax
show (allDrives |drive [trayID,[drawerID,]slotID] | drives [trayID1,[drawerID1,]slotID1 ... trayIDn,[drawerIDn,]slotIDn]) performanceStats
Parameters
| Parameter | Description |
|---|---|
|
The setting to return information about all of the drives in the storage system. |
|
For high-capacity drive trays, specify the tray ID value, the drawer ID value, and the slot ID value for the drive. For low-capacity drive trays, specify the tray ID value and the slot ID value for the drive. Tray ID values are All slot ID maximums are 24. Slot ID values either begin at 0 or 1, depending on the tray model. Drive trays compatible with HB2100/HB2200/HB2300 and HB5100/HB5200 controllers have slot ID numbers starting at 0. Enclose the tray ID value, the drawer ID value, and the slot ID value in square brackets ([ ]). |
|
Specifies the time interval for performance statistics.
|
|
Specifies the number of iterations for which performance statistics are to be collected.

Notes
The drive parameter supports both high-capacity drive trays and low-capacity drive trays. A high-capacity drive tray has drawers that hold the drives. The drawers slide out of the drive tray to provide access to the drives. A low-capacity drive tray does not have drawers. For a high-capacity drive tray, you must specify the identifier (ID) of the drive tray, the ID of the drawer, and the ID of the slot in which a drive resides. For a low-capacity drive tray, you need only specify the ID of the drive tray and the ID of the slot in which a drive resides. For a low-capacity drive tray, an alternative method for identifying a location for a drive is to specify the ID of the drive tray, set the ID of the drawer to 0, and specify the ID of the slot in which a drive resides.
The show drive performanceStats command returns drive performance statistics as shown in this example:
