Netapp note

1. Firmware upgrade:

• NetApp supports non-disruptive upgrade (NDU) for both major and minor version upgrade for SAN (FCP and iSCSI) and NFS environment. NDU is not supported for CIFS due to the protocol behavior so please make sure the customer knows it before doing the upgrade (if CIFS is using)
• take over cause about 15 seconds interrupt 
• use upgrade adviser 
•      ONTAP version is 8.0.2P3 7-Mode which does NOT support 1.2TB 10K SAS disks that comes with DS2246. A firmware upgrade to 8.1.2+ would be required. collateral device firmware and software (e.g. SnapManager) also need to be upgraded for supportability. End-user can make use of their NOW account to check for upgrade readiness and steps for their registered FAS3240 system.  

        DS2246 (IOM6) can technically be added to the same stack with existing DS4243 (IOM3) disk shelf but it is NOT recommended due to difference in speed (3G and 6G). Additional 6G SAS adapter is required for dedicated 6G stack.
  
  
  
  

2. Capacity 

A pair of SAS adpator to 5 disk shelf max.

IOM6 will not be bottle for SSD disk array in stead of IOM3

How to change the Data ONTAP 8.x simulator serial number

Data ONTAP 8 :

    First halt the VSIM and enter into the bootloader prompt. Set the new  serial ID there as shown.

     SIMLOADER> set SYS_SERIAL_NUM="987654-32-1"

     SIMLOADER> boot

   On booting if the system complains that it can't find it's disks then that's because software disk ownership is doing the right thing and keeping the disks allocated to the older system (old serial number). If so, ctrl-c into 

   maintenance mode and re-assign the disks to the new ID.
