Do anyone know why controller hangs when adding new disk enclosure to the EVA 4400. the EVA FW 0900100. I Opened one loop and added the enclosure and it is working fine and i can see the new encl and the new disks. Once i added the second loop the whole storage hangs. and hosts disconnected.
yes was ok.and when i opened one loop and connect the new encl it is ok too. once i connect the sec ond loop to the new encl ... the EVA becomes unavailable. this is the issue
XCS 09001000 is quite old and a number of improvements have been made since the first release. As the support for this version has been set to 'inactive' on 31 January 2009, an upgrade is recommended.
If upgrade is recommenedSo for which version because the latest versions have many issues.
and to add a disk enclosure i think it should go smoothas this eva could come with 2 or 3 or 4 disk encl . i think if we upgrade it from 2 disk encl to 4 disk encl it should go smooth.
If it has firmare 09001000 that means it's old, and that means that it could have the old cables, with a plastic tab on the connector. Those cables cause trouble on the controllers when disconnected.
Also, after adding the enclosures to one loop, was it working OK?
You are right it has the old cables and the FW is old. But when i added it to one loop it was ok ( No HANG). Once i connected the second loop it hangs and it became unavailable.
Sounds like you are talking about this advisory (I've found them on several EVAs - some even delivered in late 2008, but maybe they have been in stock for some time):
c01524604 - ADVISORY: HP StorageWorks 4400 Enterprise Virtual Array controller shutdown could affect availability
