Modify Copy Parameters

This function specifies the threshold for the SDP usage ratio and sets an SDPE. If the SDP capacity is
insufficient during a SnapOPC+ session, an error occurs and the relevant copy session and all the copy sessions
that started earlier than the relevant session are stopped. This function is used to change the threshold and
the SDPE.
Registering a license for the Advanced Copy function or the Unified Storage environment is required to use
this function.
• Threshold setting for SDPs
- Automatically notifying the user when the SDP usage ratio exceeds the threshold can be set. To notify
events, specify the notification method in advance. Refer to
144)
- If the threshold for multiple policies is satisfied at the same time, the ETERNUS DX notifies of the
highest policy level.
- Notification of the shortage of SDP capacity is sent only once for each policy level. Even if the
threshold is exceeded again within the 24 hours from the first notification, the ETERNUS DX does not
report that effect. After 24 hours has passed, the device sends a notification again.
• SDPE settings
- The current capacities of SDPEs and SDPs can be checked. Refer to "Snap Data Pool" in "ETERNUS Web
GUI User's Guide (Operation)" for details.
- The maximum SDP capacity is determined by the SDPE. The maximum SDP capacity for each SDPE is
described below. Note that the maximum SDP capacity varies depending on the maximum physical
capacity of the drives in the ETERNUS DX.

ETERNUS DX500 S3/DX600 S3
ETERNUS DX8700 S3/DX8900 S3
ETERNUS DX200F
- When an SDPE is changed during operation, the changed value is applied to the SDPEs for the SDPVs
that are created. Note that values of the SDPEs for SDPVs that are already created and being used do
not change. Determining the SDPEs before starting operations and not changing the SDPEs once
operations start are recommended.
