EMC DMX-III question AS/400 and V5R3M5
 

Technical question:

We have a rather uncommon setup on a number of AS/400 systems
partitions in that they use external SAN disk, not internal spindles.
They work pretty well, and some machines even use a load source
emulator card (ie. NO internal disk at all). 'D' IPLs, DR tests,
system rebuilds are a little bit tricky and fun, but quite workable.

The problem is that with V5R3M5 the AS/400-based EMC menus fail, and
can/have caused unexpected IPLs when least expecting it! For example,
when attempting to break external SAN mirrors on a production machine.
We basically have to rely on our SAN tech. team to break/restore
mirrors.

I can't seem to get a straight answer from EMC patches/fixes for
the AS/400. As far as I can tell EMC DMX-II and DMX-III drives are
only theioretically supported on a maximum OS/400 level of V5R3M0. Any
ideas anybody? All assistance appreciated. . .

I believe M5 increased the minimum required size of the load source
disk(s). If the emulator card can be reconfigured to present a larger
disk size to OS/400, that might help.

Thats not that uncommon of a config ...

You probably have a bad combination of Enginuity (the symm os), LIC
ptfs and SRDF TimeFinder Manager (the EMCCTL Library containing
SYMAPI) revisions. Get EMC support and get directly to the L2 iSeries
support group in the US.

If you are running V5R3M5 and have PTFs MF38149 / MF38939, you have to
use 5.3 or later of timefinder manager. IBM changed something to do
with object digital signatures. GO EMCCTL/MAINCTL Option 4 to see
what version you are running.

If the sync/split menus are failing that would be my guess. The other
thing i can think of is that timefinder isn't communicating with your
gatekeeper lun correctly.

TimeFinder 5.3.01 release notes indicate support for V5R3, V5R3M5, and
V5R4.
TimeFinder 5.4 was released 4/2007
