Item Business Copy Snapshot
- In the case of using virtual DKC which straddles multiple
physical DKCs, make sure that virtual LDEV ID is not
duplicated in virtual DKC.
* In the conventional environment where the RSG function
is not used, LDEV ID has been assigned in the
meta_resource (RSG#0) by default.
To use the Ext Stor function, newly create RSG#N.
Since LDEV ID has not been assigned in RSG#N, usable
LDEV ID in themeta_resource (RSG#0) needs to be
assigned to RSG#N.
[LDEV ID assignment procedure to RSG]
(1) Remove the assignment of virtual LDEV ID from the
physical LDEV ID which is assigned to RSG.
(2) Assign the physical LDEV ID to RSG which P-VOL
belongs to.
(3) Assign the virtual LDEV ID to the assigned physical
LDEV ID.
[Before assigning LDEV ID] [After assigning LDEV ID]
16. When configuring Ext Stor, if the pair operation of
Business Copy and Snapshot pair is performed, create a
Host group name: "HP-VSS-HG" in the RSG which P-VOL
belongs to.
17. If virtual DKC straddles multiple physical DKCs and
THP pool/Fast Snap pool is used in the configuration that
the backup target is placed in each physical DKC, the
pool number and pool type used in each physical DKC
needs to be identical.
