Context is in reclamining a Mask and SG , had done for far:
symaccess -sid xxxx delete view -name bert -unmap # interesting this clearly didn't unmap devs
symaccess -sid xxxx delete -name bert -type storage -force
symdev -sid xxxx -devs 0474,063A,068A:068F free -all
####..wouldn' work as stated devs mapped or ready hence
symdev -sid xxxx -devs 0474,063A,068A:068F not_ready ....ok
symconfigure -sid xxxx -cmd "unmap dev 0474,063A,068A:068F from dir ALL:ALL;" preview
###fails with message
#### "The port attributes does not allow this operation for this microcode or SYMAPI version"
#### ..well i knew bind operations had changed in 8.3 but not sure why this won't work ... any ideas ??
####Need to get to this stage
symdev -sid 0355 -devs 0474,063A,068A:068F delete
Hope this makes sense at least to describe issue ...
Thanks ! john
Is it possible one or more of the devices in question are still in use in another masking view/storage group? If that's the case those devices would need to be removed from that SG as well. Manual mapping/unmapping is no longer supported, it is always tied with the masking operations now.
If you're certain the devices are removed from all SGs, then I would suggest opening a Service Request with Dell EMC support.
make sure your devices are not in any other storage group:
#symaccess list -type storage -sid XXX -devs 0474,063A,068A:068F
and also make sure none of the devices have snapshot/clone/SRDF connection.
if your devices are free you can try the delete command (there is no need for unamp):
#symdev free -all -dev 0474 (this process can take some time)
#symdev delete 0474 -sid 0355
