• When Resource Domains are registered in the ETERNUS DX400/
DX8000 series, the RAID Groups in which SDPVs can be created differ
depending on the current user account.
- When logged on using a Total Administrator account, SDPVs can be
created in all the RAID Groups that are a s s i g n e d t o R e s o u r c e
Domains.
- When logged on using a Resource Domain Administrator account,
SDPVs can be created only in the RAID Groups that are assigned to
the relevant Resource Domain and the Shared Resource.
• The [Set Snap Data Pool] function cannot be used in the following
conditions:
- No RAID Groups are registered in the ETERNUS DX400/DX8000
series.
- Mainframe volumes, MVV volumes, or MVV Concatenated volumes
are registered for all the RAID groups in the ETERNUS DX400/
DX8000 series.
- When all the RAID Groups registered in the ETERNUS DX400/
DX8000 series are registered in the Thin Provisioning Pool.
- When all the RAID Groups registered in the ETERNUS DX400/
DX8000 series are registered as the REC Disk Buffer.
- When no SDPV is created in the ETERNUS DX400/DX8000 series,
and the RAID Group is in the following conditions:
•
Only one RAID Group is registered in the ETERNUS DX400/DX8000
series, and LDE is in progress in the RAID Group.
• The [Status] of all the RAID Groups is not [Available], or [Present].
• The DVCF mode for all the RAID Group is [ON].
• All the RAID Groups are blocked.
• When no SDPV is created, and the maximum number of volumes for
each model is already registered, the [Set Snap Data Pool] function
cannot be used.
• Unlike other volumes, SDPV cannot be created by [Create Logical
Volume] function or deleted by [Delete Logical Volume] function.
• While SDPV can be created in any level RAID group, it is recommended
that the same RAID group configuration (same RAID level and same
number of disk drives) be used for all SDPVs created.
• The maximum capacity of SDP varies according to the unit of SDV
allocation (SDPE). The following table shows the maximum capacity of
SDP for each SDPE capacity. Refer to the "Available Capacity (GB)" in
[Snap Data Pool Information] on the [Set Snap Data Pool (SDPV List)]
screen for the available SDP capacity when creating the SDPV.
