Well, here is the status so far. 1 for 2. 50% success rate.
Applied SP5 to 2 servers. Both WERE NW6.5 SP3 prior to installation.
First server - Complete Success. Applied it, rebooted, server came up no problems. All components functioning correctly. This particular server has about 200GB NSS storage as well as iFolder services.
Second server - Crash and Burned. Applied it, rebooted. It trashed my NDS database. Server otherwise came up fine, but NDS wouldn't open with -723 errors. Could not repair it. Could not even try to repair it (abort with -6007 errors). The files required for repair did not exist. Found that the file SYS:_NETWARE\NDS.DB had been deleted. Gone. Nowhere to be found. Luckily I was able to grab a backup copy of this file and put it back in place. Other people might have been screwed. Many of the TIDS that you read about this error give you the pleasant option of removing and reinstalling NDS on the server. This would have sucked since this server is my Master of [root] replica and also my Org CA. It has about 100GB of NSS file storage. All of the file system seems to be okay, and it appears to be working now that NDS is repaired.
RECOMMENDATION.. if you apply SP5, make a backup copy of NDS first. You can do this with various methods, but a very straightforward way is this. Copy all the DS files into a backup directory. The following is a good way to do this at the server console.
Unload DS
Load TOOLBOX -NL (Toolbox should be on your system.)
CD SYS:_NETWARE
PWD (Verify that you are in the SYS:_NETWARE Directory)
MD SYS:\DSBACKUP
COPY *.* SYS:\DSBACKUP\ /S
Load DS
Should you need to recover files, you can pull the files out of there as easy as you put them in. This method keeps the files in their raw format for easy recovery if necessary.
