Hello All,

We're starting the planning for an upgrade of a v3170 from 7.3.5.1P5 to 8.0x or possibly 8.1GA 7-mode (we've already upgraded another filer to 8.1 without trouble). The system is backed by a 3Par T800 serving up LUNs as "disks" for the v3170 with all NetApp aggregates in essentially RAID0 (redundancy is provided at the SAN level).

The v3170 is heavily used with a long list of protocols and features enabled including autohomes, de-dupe, vfilers serving CIFS, NFS, and iSCSI. NFS is v3 and v4, sometimes Kerberized, sometimes auth_sys. iSCSI is CHAP authenticated, sometimes using native initiators and sometimes SnapDrive and/or SnapManager for SQL. Backups are via NDMP to a CommVault system. Our enterpise SQL clusters are served (iSCSI) as well as our main VMware Farm (datastores are via NFS).

I welcome feedback from anyone with experience in this type of effort. My sense is that the biggest dependencies will be on connected SnapDrive and SnapManager clients. For example, is there a way to identify all connected SnapDrive and SnapManager clients and their versions?

Hope to hear from you,

Randy Rue
