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

Parameter	Description
`allDrives`	The setting to return information about all of the drives in the storage system.
`drive` or `drives`	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 `0` to `99`. Drawer ID values are `1` to `5`. 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 ([ ]).

allDrives

The setting to return information about all of the drives in the storage system.

drive or drives

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 0 to 99. Drawer ID values are 1 to 5.

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 ([ ]).

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:
