Commands to create a local Clone from R2 devices
Hi,
We need to create local Clones from SRDF R2 copies at a remote VMAX for DR purposes.
I need to automate it from a Unix server so we can take regular copies.
Can anyone point me in the direction of a document which shows exactly how to do this please ? I just need the symcli commands.
I've had a look at the white paper here ( https://www.emc.com/collateral/white-papers/h8981-vmax10k-timefinder-recoverpt-local-repl-wp.pdf ) but it's missing most of the commands I need.
Many thanks,
Steve.

The basic clone command syntax is:
symclone -g dg_name -tgt create -diff | activate -consistent | recreate | terminate
I suggest you take a look at the Solutions Enabler Timefinder CLI product guide for more detail...
For example, The -RDF parameter can be added if running the clone of the R2 from the R1 side.

Thanks for the advice Jason. I've followed the steps in the Timefinder CLI guide which I belive are thus,
1. Check status of RDF group
symdg show ax061_2
2. Add remote target into RDF group
symdg -g ax061_2 add dev 024B -rdf -tgt
3. Check okay
symdg show ax061_2
Standard (STD) Devices (2):
{
----------------------------------------------------------------------------------
Sym Device Cap
LdevName PdevName Dev Config Att. Sts (MB)
----------------------------------------------------------------------------------
DEV001 N/A 29C2 RDF1+TDEV RW 33792
DEV002 N/A 29C3 RDF1+TDEV RW 33792
}
TGT Devices Remotely-associated (TGT RDF) (1):
{
----------------------------------------------------------------------------------
Sym Device Cap
LdevName PdevName Dev Config Att. Sts (MB)
----------------------------------------------------------------------------------
RTGT001 N/A 024B TDEV RW 33792
}
4. Establish clone pairs for targets and source devices
symclone -g ax061_2 establish -full -rdf DEV001 -tgt ld RTGT001
Execute remote 'Full Establish' operation for the 3 specified devices
in device group 'ax061_2' (y/ ) ? y
Remote 'Full Establish' operation execution is in progress for the device list in
device group 'ax061_2'. Please wait...
Could not select requested device(s) from the specified device group
Anyone seen this before ?

Just FYI -- if you're writing your own automation to periodically refresh a Gold BCV/Clone off of SRDF/A R2 volumes, you may also want to consider using symrecover for this. In addition to providing a built-in mechanism for recovering from SRDF/A session drops (CACA errors), symrecover also has functionality for periodically refreshing BCVs/Clones off of Async R2 devices. The Solutions Enabler SRDF CLI Guide has more detail on symrecover options & settings.
Thanks,
- Sean

There is a slight syntax issue in the establish. This will work:
symclone -g ax061_2 establish -full DEV001 -tgt sym ld RTGT001
