Interesting bug! that is supposed to be fixed in DSM 4.0 – http://support.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=591952
|Title||Long boot times may be observed with Data ONTAP DSM 3.5|
|Bug Severity||2 – System barely usable|
|Bug Type||ONTAP DSM|
If a Windows Server host is running Data ONTAP DSM 3.5, long boot times may be observed. The boot time will vary based on the number of mapped LUNs and paths per mapped LUN. Boot times will be approximately 3 seconds per path, per LUN.
Reduce the number of mapped devices during Windows Server OS boot. You can do this several ways, which includes disabling the initiator ports before reboot or taking the mapped LUNs offline before the system startup.
