No: You cannot perform the task (the command is rejected).
You can perform ShadowImage pair tasks after you store snapshot data, but
the consistency of the stored snapshot data is not guaranteed.
Thin Image S-VOLs use the data in the P-VOL. You cannot Quick Restore in
ShadowImage.
For more information about ShadowImage tasks and pair statuses, see the
Hitachi ShadowImage® User Guide.
Caution: Thin Image uses MU numbers 0 to 1,023, and they are assigned in
the order of 3 to 1,023, followed by 0 to 2. ShadowImage uses MU numbers
0 to 2. Thin Image cannot use the MU numbers 0 to 2 if you want to share
Thin Image volumes with ShadowImage.
To share Thin Image volumes with ShadowImage if Thin Image is using the
MU numbers 0 to 2:
1. Delete the Thin Image pair of the MU number 0 to 2.
2. Create the ShadowImage pairs and Thin Image pairs.
Sharing Thin Image volumes with TrueCopy and Universal Replicator
You can share Thin Image (HTI) P-VOLs with TrueCopy (TC) and Universal
Replicator (UR) pair volumes.
