Boot Disk not available

catastro — Mon, 14 Apr 2008 07:20:17 GMT

Hi to all. I have a hard question. I have a problem on an L2000 server running HPUX 11.00 (it is old, but next month will update it). One of my boot disk is failling continuously. I have replaced it already three times for brand new ones, and even the disks backplane. I tried changing the disk from on slot to another and after making it work a while with dd, I rebuilded the mirror with that slot. The thing is that around one day after, the problem start again, with NO_HW in ioscan, in vgdisplay is unavailable, and lvols are in stale mode (but not all. lvol2 is syncd). I have no idea of what else I can do.
I send you a file with the outputs of ioscan, vgdisplay, and the syslog lines where the problem started again to reproduce, and as well as the ems notification.
Thanks for your help

Hi,

This should be a h/w problem. Do you have any error message on the GSP? If you have tried to change the disk/media backplane, next thing you should try on is the LAN/SCSI Core I/O Board.

Catastro,

if your hw failed quite frequently, please log case to HP for advise.

This is to prevent from further more unplanned downtime

Thanks Sandy. IÂ´ll open another case for make the I/O card to be changed. In case it doesnÂ´t help, what else could be?
It all started like a week ago or so, and before this, all was going perfect.

Hi Catastro,

I think next thing you should try is the IO Backplane. Anyway you better asked hp response center to do more thorough diagnostic. They are the expert on this things anyway.
