Upgrading your OS

In general IBM does a pretty good job of outlining how to do an OS upgrade. The basic rules of thumb are to:

  • Read carefully all applicable Memo To Users. If you are at x.y and you are upgrading to x.y+2 then read the MTU for both x.y+1 and x.y+2. IBM will not repeat everything in x.y+1 in x.y+2. So, if you are upgrading from IBM i 6.1 to 7.2 then read the MTU for both 7.1 and 7.2. From 7.1 to 7.3 then read the MTU for both 7.2 and 7.3.
  • Following the instructions in the Knowledge Center carefully.
  • Verify that your hardware is compatible with the new release. Do not just check the model. Sometimes ancillary items are important also. For example a Power 6 could have upgraded to IBM i 7.2 but often times many cards and disk enclosures were not supported under 7.2.
  • Check with your software vendors to ensure that the version of software you are running is compatible with the new level of OS.

Change in functionality with NetServer shares due to SMB2

IBM's change to using SMB2 as a default with 7.3 has caused issues with some users. Basically it's important to be on current Windows versions and they be currently patched. A specific fix is mentioned here: http://www-01.ibm.com/support/docview.wss?uid=nas8N1021348 There was also an issue with this and your password case but I can't find that link. One technique used is to change 7.3 to go back to SMB1. Since someone compared that to fixing a security issue by just giving all users *ALLOBJ authority I'll not pass on the link which shows you how to switch back to SMB1.
