Setup a standard/BCV device pair?POSTED BY DIWAKAR
In order to use the control functions of Solutions Enabler, you
must create device groups and
add/associate Symmetrix devices with the group. The following
example shows how to create a device
group, add a standard device to it and associate two BCV devices
to the group.The following commands will create a device group
using the default type (regular). Next we will add a
device to the device group and assign it a logical name. Then we
associate two BCV devices with the
device group so we can switch back and forth with the BCV
devices.
symdg create mygroupsymld -g mygroup add dev 000 STD000symbcv -g
mygroup associate dev 110 BCV000symbcv -g mygroup associate dev 111
BCV001
NOTE: At this point you have only added/associated devices with
a device group. These actions do not in
any way describe which devices should actually be paired. This
may be confusing as the documentation isnot very explicit. The fact
is that the symmetrix may already have BCV pair information about
these
devices depending on how they were used in the past.
Now issue the commands to define the STD/BCV pair and actually
synchronize the pair with a full
establish.
symmir -g mygroup -full establish STD000 BCV dev 110
or
symmir -g mygroup -full establish STD000 BCV ld BCV000
This explicit definition of the STD device and the particular
BCV device will cause any existing pairinformation to be
disregarded and will use this new information to create a pair.
This is
comparable to the older TimeFinder Command Line Interface "bcv
-f filename" where the file "filename"
consisted on one line entries pairing STD devices with BCV
devices. And finally, split this TimeFinder pair
and synchronize the STD device with a different BCV device.
symmir -g mygroup split
symmir -g mygroup -full establish STD000 BCV dev 111
Another method to establish pairs, using the "-exact" option
[Available in V3.2-73-06 and higher]The -full
-exact options on the symmir command instructs SYMCLI to define
the STD/BCV pairs in the same order
they were entered into the device group.
symdg create mygroupsymld -g mygroup add dev 000 STD000
symld -g mygroup add dev 001 STD001
symbcv -g mygroup associate dev 110 BCV000
symbcv -g mygroup associate dev 111 BCV001
symmir -g mygroup -full -exact establish
