Q :  the Oracle VM administrator is asking me about a page 83 item which seems to be different on each LUN / Replica LUN pair. He says the page 83 item needs to be identical on each Primary / Secundary LUN pair.  Finally, tried to test this out in lab and noticed that, it cannot be identical as the page 0x83 scsi id derived based on WWN (in my test, it just added number 3 in front of wwn).   In Unity, Replication creates a new dest lun first (different wwn) and then it syncs data from source.  service[NAME] spa:~> uemcli -no /stor/prov/luns/lun show -filter WWN  1    wwn = 60060160b71a7820f668e4585f5b68d4 (this is source lun) 2    wwn = 60060160b71a78209971e458c77bdf44 (this is dest lun)  And a remote unity array as dest:  service[NAME] spa:~> uemcli -no /stor/prov/luns/lun show -filter WWN  1    WWN = 60:06:01:60:B9:3A:78:20:5D:67:E4:58:62:FA:6C:15 (dest)  At a linux host:  [root[NAME] ~]# /usr/lib/udev/scsi_id --page=0x83 --whitelisted --device=/dev/sdb 360060160b71a7820f668e4585f5b68d4 [root[NAME] ~]# /usr/lib/udev/scsi_id --page=0x83 --whitelisted --device=/dev/sdc 360060160b71a78209971e458c77bdf44  [root[NAME] ~]# /usr/lib/udev/scsi_id --page=0x83 --whitelisted --device=/dev/sdd 360060160b93a78205d67e45862fa6c15  
I have 2 Unity 400 arrays and synchronous replication is in place for a couple of LUNs. From Unity 1 I'm replicating a LUN to Unity 2 and also the other way around. I have an Oracle VM cluster attached to each of the two arrays and the Oracle VM administrator is asking me about a page 83 item which seems to be different on each LUN / Replica LUN pair. He says the page 83 item needs to be identical on each Primary / Secundary LUN pair.  I don't know where to set this data and one of the posts I can find on this is one from 2008 which addresses a Symmetrix and some SPC-flag.  Does anyone know what this page 83 thing is about?
