This level of control is performed when the sidefile capacity is equal to or larger than the level-2
threshold, and is smaller than the level-3 threshold.
Write I/Os to volumes are put in a wait status by SCP-SCI reporting when the SCP-SCI reporting
threshold (for example, level-2 threshold) is exceeded.
• Level 3
This level of control is performed when the sidefile capacity is equal to or larger than the level-3
threshold.
Note: Sidefile puncture will occur. (The puncture threshold is the sidefile threshold plus 10%.)

• Level 1 Sleep
Use to specify whether the storage system should perform Sleep - Wait command retry when the
sidefile threshold exceeds the sleep wait threshold (for example, the level-1 threshold).
• Enable radial button
The storage system performs a Sleep - Wait command retry.
• Disable radial button
The storage system will not perform the Sleep - Wait command retry.
Note : Level 1 Sleep is always set to Disable when Block Option is set to Volume Level.
• Sleep Time
Use to specify the sleep wait time for Sleep - Wait command retry.
• 10ms
The storage system waits 10 milliseconds.
• 100ms
The storage system waits 100 milliseconds.
• Level 1 SIM
Use to specify whether the storage system should report a SIM (service information message) to
the host when the sidefile threshold exceeds the sleep wait threshold (for example, the level-1
threshold).
