Let's say we have a fcalias which contains a group of tape drives. This drive group alias is already a member of an active zone
zone name tapeserver_tapedrive vsan 10
member fcalias tape_drive_group
exit
Now I am adding a new drive into the group. Do I also need an update of the zones in which the fcalias is a member of?
!! add a new drive into the group
device-alias database
device-alias name IBMXXXXXX pwwn xx:xx:xx:xx3:xx:xx:xx:xx
device-alias commit
fcalis name tape_drive_group vsan 10
member device-alias IBMXXXXXX
exit

Sorry, you are talking about 2 types of alias, which are different: fc-alias and device-alias; fc-alias is per vsan, device-alias is per fabric ?
Device alias supports two modes: basic and enhanced mode.
With enhanced mode device-alias, you can change the pwwn, and it will automatically update everywhere, without doing an explicit zoneset activation

well I am talking about fcalias and my question is about fcalias. It happens that my sample config does use device-alias inside fcalias. To make it simple, let's use fcalias only. Should I update zone config as well?
!! add a new drive into the group
fcalis name tape_drive_group vsan 10
member pwwn xx:xx:xx:xx3:xx:xx:xx:xx
exit

Do I understand you correctly, you add an additional new target pwwn ?
therefore this new target has to be included in the zone as well; the point is simply, if you do single initiator-single target, or single initiator-multiple targets; in the former, you create a new zone, in the latter, you add it in a existing zone;
The new zone has to be included in the zoneset as well.

I am adding a new target into a single initiator-multiple targets zone. Since all the targets are grouped under one fcalias 'tape-drives-group', I am assuming that just updating the fcalias 'tape-drive-group' will be good enough for this change. I know the similar operation works for device-alias in enhanced mode, but not sure about fcalias.....It will be really handy if it works.
This is what the zone looks like.
zone name tapeserver_tapedrives vsan 10
member fcalias tape_drive_group
exit

Another question: are you using enhanced VSAN zoning ?
switch(config)# zone mode enhanced vsan 3000
===> Implements changes to the zoning database and distributes it without reactivation.

After adding an additional PWWN to the FCALIAS, you do not need to:
Change the zone
Change the zoneset
However, you will need to activate the zoneset again to pick up the change.
