Drawer Dropper
We have an EVA5000 with 12 drive enclosure drawers. Over the weekend we had a drive failure in slot 14 of drawer 8. Support could not get a drive immediately and 24 hours later the drawer went red and dropped offline. The disks were unavailable and every led in this drawer was red. When support arrived they had to power every drive enclosure off, leave the controllers up, and power the drive enclosures back up, one at a time. Luckily our production data was still in tact.
Anybody else have anything like this happen with EVA storage? And if so, what was the resolution/answer as to why it happened?
Thanks

Re: Drawer Dropper
You should be careful about upgrading to VCS4 as that version introduces Active/Active controllers.
Depending on the operating systems that are accessing the array that could have big implications for you.
If there are problems in VCS3.028 then they should (hopefully) have been fixed in the latest V3 code 3.110.
As you've obviously got a support contract, ask them whether that version fixes the problems in 3.028.
Hope this helps,
Regards,
Rob

Re: Drawer Dropper
If you do upgrade then you should not go to V4.004 either !
HP do not support V4.001 or V4.004 as it should be V4.007.
As above, there are lots of things to change:
active / passive = V3.xxx
active / active = V4.xxx
you need to go from crossed cabling to straight cabling off your EVA's unless you have a CA solution already & then it should be straight anyway
If you are running Secure Path with V3.xxx THIS WILL NOT WORK with V4.xxx. You now need MPIO & DSM
If you go to V4 from V3 it needs to be done OFFLINE - HP recommended.
If you don't like V4 for whatever reason you will need to UNINITIALIZE to go back to V3!!!
You may have to update command view, depends on what you are running now....
Bottom line, read through the release notes and have a look at other posts in the itrc about this [there are several] before you just do it.

Re: Drawer Dropper
Opps , forgot to put in MPIO / DSM is a windows thing mainly but does apply to other supported OS's
OpenVMS, Tru64 built into OS so not a problem
HP-UX Secure path V3.0c for VCS V3.xxx of Secure path V4.0f for VCS V4.xxx
READ REL notes !!!
