EVA 4400 strange behaviour
I have a problem with an EVA4400. Couple of days ago one cache battery died and, after that, my hp-ux boxes
couldn't see the disks any more:
ioscan -fn
target 9 0/4/1/1.1.0.0.0.0 tgt NO_HW DEVICE
ctl 7 0/4/1/1.1.0.0.0.0.0 sctl NO_HW DEVICE HP HSV300
/dev/rscsi/c6t0d0
disk 7 0/4/1/1.1.0.0.0.0.1 sdisk NO_HW DEVICE HP HSV300
In syslog:
May 6 12:41:37 xxxxxxxxx vmunix: 0/4/1/0: Device at device id 0x10000 is back in Name Server GPN_FT (FCP type)
May 6 12:41:37 xxxxxxxxx vmunix: response, and its 'Port World-Wide Name' remains the same as
May 6 12:41:37 xxxxxxxxx vmunix: original.
May 6 12:41:37 xxxxxxxxx vmunix: device id = loop id, for private loop devices
May 6 12:41:37 xxxxxxxxx vmunix: device id = nport ID, for fabric/public-loop devices
May 6 12:41:37 xxxxxxxxx vmunix: System will be able to see LUNs behind this port
May 6 12:41:37 xxxxxxxxx vmunix: (might need to run 'ioscan' first).
The same thing for all the hp-ux servers in the SAN, also on both HBAтАЩs (0/4/1/0 and 0/4/1/1, all servers have 2 FC HBAтАЩs)
I checked the SAN (cabling, switch configurations, no problems there) and still the same problem.
Curiously enough production still works (probably until the clusters will restart), we also have 2
MS WIN 2003 clustered in this SAN but they crashed.
Somebody advised me to update the firmware on the EVA4400 (recommended version 0090005000) but I cant access the storage using command view and I donтАЩt know how to use the management port.
Did somebody else have a similar problem using eva?

Re: EVA 4400 strange behaviour
are you missing all HSV300 disks on the servers or just some ? It is possible that only some of the paths have failed.
Secondly, firmware upgrade via the management port on the EVA is not possible. You have to use Command View.
There was a whole bunch of problems reported with EVA4400 over the last few weeks. I suggest you start with opening a case at HP.

Re: EVA 4400 strange behaviour
All the paths are affected and I was speaking about MFG port not the wocp port. Are you sure that using MFG port you can't update the firmware?
thanks in advance.

Re: EVA 4400 strange behaviour
You would then see half the paths to each vdisk lost, but if you have a multipath software like SecurePath or have created multiple possible paths using PVlinks, the access to LUNs should not be lost.
The fact that you have lost access from Command View means that something else has happened. This requires an analysis of the EVA logs. Try to restart Command View service too.
Latest firmware for the EVA4400 is 095011000, you can also update the management module to 0001.2100, and you'll have Command View 9.01 inside there.

Re: EVA 4400 strange behaviour
if all paths were lost, even your Serviceguard would not be able to handle the problem. Once nothing is presented, even HPUX can not see the vdisks. More likely, you have lost only paths to one controller, as vcespon suggests.
Check:
# ioscan -fnC disk
# spmgr display
Your inability to access the EVA is a separate problem. Has already HP been informed ? (ISEE should have logged a call about CV being unable to manage the EVA).
