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. . . Regards, Greg Chijoff EDS Sydney Australia |

EMC DMX-III question AS/400 and V5R3M5
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. |

EMC DMX-III question AS/400 and V5R3M5
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 |
