Format

sio show queue sdid=?

sio show queue sdid=? usermode

Parameters

Parameter

Description

Value

sdid=? Physical ID of a disk.

To obtain the value, run the "sddebug show disk" or "sddebug show disk -app_data" command. Run the latter command in user mode.

usermode
  • When this parameter is mandatory, the current command can be used only in user mode.
  • When this parameter is optional, the current command can be used in both user mode and kernel mode.

The value is "-app_data" which indicates that the command is executed in user mode.

Views

Diagnostic view

Usage Guidelines

  • Run the "sio show queue sdid=? -app_data" command to query the I/O queue information on a specified disk in user mode.
  • Run the "sio show queue sdid=?" command to query the I/O queue information on a specified disk.

Example

  • Query the information about the I/O queue on the disk whose physical ID is "32".
