vgchange: Warning: Couldn't attach to the volume group physical volume I/O error
I have problems mounting my FS. Each and everytime I am mounting my FS this message shows up:
root@csp_dev[/]# mount /dev/vgcx7_0810orahome/lvcx7_oraclehome /oraclehome
/dev/vgcx7_0810orahome/lvcx7_oraclehome: No such device or address
I tried to activate the VG by using vgchange command like this: vgchange -a -y /dev/vgcx7_u07b, but another error showed up:
root@csp_dev[/]# vgchange -a y /dev/vgcx7_u07b

Your connection to storage has been broken.
Check:
* Power on storage array
* Power on fiber switch if present
* cabling.

Re: vgchange: Warning: Couldn't attach to the volume group physical volume I/O error
You can do simple tests to check if your storage devices are ok !! ..
1 - Check the status ( ioscan -fn, ioscan -funC disks )
2 - Check the disks ( diskinfo /PATHS_to_devices )
3 - check the i/o ( dd if=/path_to_device of=/dev/null bs=1024 )
You must have a hardware issue !!
Check the cables
Check HBA's
ioscan -funC fc
fcmutil /path_to_HBA's
If you have any dout please reply !!
