As you can see in
, if both the P-VOL and S-VOL have VMA, the P-VOL's VMA
is copied to the S-VOL. In
, the S-VOL's access attribute is Read/Write when
the pair status is SMPL. After the P-VOL's VMA is copied to the S-VOL, the S-VOL's access attribute
becomes Read Only, which is the same as the P-VOL's access attribute of the P-VOL. Note that
when the pair status is PAIR, copied information about the access attribute is not effective, so the
S-VOL's access attribute is still Read/Write. To make the copied information about the access
attribute effective, suspend or delete the pair with the Pairsplit-r or Pairsplit-S operation and make
the pair status PSUS or SMPL. However, even if the pair is suspended, the S-VOL Disable setting
is not effective. To make the S-VOL Disable setting effective, delete the pair. For more information
about pair status and operations related to the access attribute, see
.
NOTE:
If the pair is suspended or deleted during the COPY status, the P-VOL's access attribute
is not copied to the S-VOL. To copy the P-VOL's access attribute to the S-VOL, ensure that the pair
status is PAIR, and suspend or delete the pair.
NOTE:
When the P-VOL is in the COPY or PAIR status, there are two access attributes that can
and cannot be changed according to the existing access attribute. For more information about the
variable access attribute, see
