Failing over NAS to mirror

[acl03]

We had one of our HP Storage servers fail today. I was able to successfully failover to our DR box using OpenView Storage Manager software.

I ran this script(written by someone who left the company). Iunderstand what the dnscommand lines are doing, but I don't understand what the point of the setspn lines. Anyone know what they are for?

dnscmd 150.142.153.12 /RecordDelete cehad.mycompany.com cehnas1 A 150.142.153.21 /f
dnscmd 150.142.153.12 /RecordDelete 153.142.150.in-addr.arpa 21 PTR cehnas1.cehad.mycompany.com /f
dnscmd 150.142.153.12 /zonerefresh cehad.mycompany.com
dnscmd 150.142.153.12 /zonerefresh 153.142.150.in-addr.arpa 
dnscmd 150.142.153.12 /RecordAdd cehad.mycompany.com cehnas1 A 150.142.48.29 
dnscmd 150.142.153.12 /RecordAdd 48.142.150.in-addr.arpa 29 PTR cehnas1.cehad.mycompany.com
setspn -D HOST/CEHNAS1.cehad.mycompany.com CEHNAS1
setspn -D HOST/CEHNAS1 CEHNAS1
setspn -D SMTPSVC/CEHNAS1.cehad.mycompany.com CEHNAS1
setspn -D SMTPSVC/CEHNAS1 CEHNAS1
setspn -A HOST/CEHNAS1.cehad.mycompany.com CEHNASDR
setspn -A HOST/CEHNAS1 CEHNASDR
setspn -A SMTPSVC/CEHNAS1.cehad.mycompany.com CEHNASDR
setspn -A SMTPSVC/CEHNAS1 CEHNASDR

Thanks,

SPNs help a client find a computer account.

This server is simply a file server. What services does it offer that would require an SPN change?

I see that it is changing SNMP and HOST attributes....what exactly do those do?




Thanks,
