11 to 11i OS upgrade

[klb]

I've got an N4000 with an attached fc60 array running 11.00. Need to take this to 11.11.

A read of the archives here indicates that upgrading vs. cold install may be troublesome, however I think I'll try it anyway.

Any gotchas with respect to the FC60? Should I expect to "see" the defined LUNs post upgrade ( or even cold install ) just as they existed prior?

Unfortunately I don't have a test system with this same configuration so I'm going to be flying blind.

This box also has an ANSI/C compiler installed and licensed but we don't have the license certificate and can't find any documentation. I suspect the upgrade ( and certainly a cold install ) will render this software useless. Any advise here?

Thanks,

All these questions are some of the reasons for the upgrade process to be scary.

ANSI\C will probably not work. You will need to upgrade all your products along with your OS ( if you don't you would only be lucky if they continue to work).

There should be no issue with your fiber connections unless there is a new driver with 11.11 ( probably is) that would cause a device renaming.

As you stated, the way to work these issues out is to test, in your case test on the only box you have.

Make sure you have Ignite backups and data backups, document all LVM configs you have. It may upgrade sucessfully and non of this will matter.

My experience is that either there is an error during the new kernel build that fails due to a driver issue or it dies during disk swap( cannot remember is 11.11 is a two CD set). Both leave you with a now unusable system. ( this is what the ignite image is for).

To solve the second issue swcopy off all CDs to disk.

No, the C compiler has no idea anything changed but may not like the new OS version.
