Write disable device on certain FA port
I have some devices not being unmap in clean during the provisioning. Now I need to perform OR hot push so I was thinking to unmap the devices from those FA that was not used by host. I cannot write_disable the entire device to perform the clean up.
I checked the manual I can peform write_disable the device from unused FA and unmap. I just to check whether this will impact the production.
symdev -sid 1234 write_disable ABC -SA 3a -p 0

If the devices are NOT in use by the host (meaning they don't utilize a path to the FA you want to WD them on), then it should be fine as the host is not aware of that path anyways and shouldn't impact production to WD on that single FA.
As for OR, if that is being used on these devices, check the OR guides since the relevant hot-push requirements around zoning all FA's to each other that have mapped devices varies between VMAX and VMAX3. I'm not sure what type of box this is so that is why I say it varies and those rules should be reviewed.
