Ok, the SAV devices are well laid out, but I would rather see one on every disk.  They are on 60 out of 116 active disks.  Not sure why you are thinking of enabling DSE.  Again I would get your local account team involved in this.  There are cases where enabling DSE won't help.  RDF/A will still drop and the time to recover will be longer.  There are also cases where it will work great, and keep RDF/A from dropping.  Someone will need to look at your use case and workload to see which bucket you fall into.
Hi Guys,  I am trying to create a DSE pool in VMAXe 10K. I have created a pool of type rdfa_dse. I have around 30 savedev's that are in default_pool, I want to move them to the DSE pool.  The procedure im following is to first disable the device from default pool then add them to dse pool.  symcli is not allowing me to disable the devices in default pool, below is the error, Any suggestions are welcome  C:\>symconfigure -sid 73 -cmd "disable dev 010B in pool DEFAULT_POOL type=SAVEDEV;" preview Execute a symconfigure operation for symmetrix 'XXXXXXXXXX' (y/ ) ? y  A Configuration Change operation is in progress. Please wait...     Establishing a configuration change session...............Established.
