Re: lvm problem - Help!
Are the controllers identified in the ioscan. Can you attach your ioscan output for us to look at.
Hope this helps.

Re: lvm problem - Help!
Make sure that ur DS2100 is powered on and connected to the system properly. Don't hang on doubt, Please remove cables and cross check it. Then boot the system
#ioscan -fnC disk
Look for the device file corresponding to that 4 disks. If U are not able see thos, We can't blame LVM, Something is wrong with ur DS2100 or it's interface. If this is the case sort it out with H/W vendor.
Fortunately, If U are able to see the device files here, then
#strings /etc/lvmtab
Make sure that those device files are listed here under the concerned VG. If not there, do this
#vgscan
If entry is there in /etc/lvmtab, then
#vgchange -a y -q n vgxx
I hope now will be able to trace the problem
Best of luck

Re: lvm problem - Help!
In addition to the suggestions thus far; assuming that you can see CLAIMED devices with 'ioscan', a useful probe is to interrogate the device with 'diskinfo':
# diskinfo -v /dev/rdsk/cXtYdZ
Functional disk will return a *non-zero* size along with other information.
Regards!

The ds2100 is c6t0d0;
The cables are ok. The leds indicates that de disk are powered. I did vgexport but when I try to import I get the message:
Could not open Physical Volume "/dev/dsk/c6t0d0".
I think is hardware problem
Now the technician is comming...
Thanx to everyone...
