We recently received a new dmx4. The bin file delivered had a vcm volume (042) and 48 gatekeepeers (043 - 072). I am connecting the first windows host (ecc server that runs SE and SMC) to 8a1 and 9a1. The bin file had 042 (vcm) mapped to 8a1 and 9a1. It also had 8 gatekeepers on 8a1 and another 8 on 9a1. I masked these to the two hbas on the windows host. Below is the output from the sympd list. Do I really need 16 gatekeepeers for this host? Can I map and mask these same gatekeepers to other hosts? When going into windows diskmgmt, it is strange to see 18 small 3MB devices (8 gatekeepers and 1 vcm on each FA port).

yeah, you can map/mask them to multiple hosts. If you are going to be doing a lot of symcli work from this box, also considering you have ECC agents doing its polling ..i don't think it will hurt to have that many.
you can use symgate command to define them as gatekeeps and then associate them with a device group. This way these gatekeepers will be the first devices used for any symcli calls.
gatekeepers are the channel used by symcli to "talk" to our storage... defining a gatekeeper and adding it to a DG will force symcli in using specified gatekeeper instead of a generic (pooled) one. In case the defined gatekeeper is unavailable (first device used) symcli will find a pooled GK to serve the request.
Can you please briefly explain more about symgate commands and when we add the to a device group...how will they be the first devices used for any symcli calls?
