EVA5000 VCS 4.x - 3.x Downgrade?

[Ian Dennison_1]

Have a trash-and-burn EVA-5000 that I am using for testing VCS Upgrades and OS patching that is required as part of it. I cannot seem to downgrade the VCS from 4.100 to 3.110, even after de-initialising the Array.

Also, when I did upgrade the VCS and recable the SAN, only half the device paths were visible in "ioscan -fn"; the rest were "UNKNOWN". Even using the Fibre-Channel-00 driver install did not bring them back. Eventually I had to re-install SecurePath (Active/ Active instead of Active / Passive) then de-install it to get the devices recognised.

Has anyone seen these before and know how to work around them?

Share and Enjoy! Ian

Hmmmm, got it working. You can't use the GUI, you have to un-initialise the Array, use SSSU to select the un-initialised Array and then perform a "codeload [path to SSS file]". Once this is complete (wait for the codeload on the trays and disks to complete), you can initialise the Array.

10 points to Hufflepuff there. Share and Enjoy. Ian

Hi Ian,
To go from VCS v4.x to v3.x you must uninitialise the array before the codeload. I have done this many times no problem from CV. I have also done the un-init from CV or the OCP - no problem. Alos the versions you specified = all OK. The key thing is to un-init first or it will fail.
Are you using HP-UX as the OS? If so what version as this is where you can have fun with SP or MPIO as most people call it!
Assuming HP-UX for VCS VCS V3.xxx (A/P) you need SP V3.0c for VCS V4.xxx (A/A)you need SP V3.0f. Both versions can co-exist on the same platform and you would need both if you are using both versions of VCS. If you do not use them you can still use pvlinks.
I believe that this is correct up to HP-UX 11.23. For 11.31 the it is native.
Type in "spmgr" for V3.0c and "autopath" for 3.0f and you will see what params/qualifiers you have available for each cmd.
Alternatively put in "swlist" and look for the products.
