vgchange: Warning: Couldn't attach to the volume group physical volume I/O error

Hi Guys,

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
vgchange: Warning: Couldn't attach to the volume group physical volume "/dev/dsk/c43t6d2":
I/O error
vgchange: Warning: Couldn't attach to the volume group physical volume "/dev/dsk/c37t6d1":

vgchange: Warning: Couldn't attach to the volume group physical volume "/dev/dsk/c37t5d7":

so on so forth...


What seems to be the problem here guys?

Shalom,

Your connection to storage has been broken.

Check:
* Power on storage array
* Power on fiber switch if present
* cabling.

Hi

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 !!
