Problem to mount file system

[Ali_11]

Hi,

After a reboot , some FS was not mounted.
I try to mount them and i have that message : "mount - Cannot open /dev/vg01/lvol3: No such device or address" for all the FS not mounted.

What can i do to resolve the problem ?

Thanks.

Hi,

please check if vg01 is active:

# vgdisplay -v vg01

Is there running MC/SG? If, then check /etc/lvmrc if vg01 should be mounted automaticly after reboot. If there is no MC/SG running then activate the volume group:

# vgchange -a y vg01
# mount -a

If no errors all filesystems in vg01 should be mounted now.

check /etc/lvmrc as whether it has entry for auto enabling vg01 after reboot.

just do a
#vgchange -a y vg01

Armin,

When i try do activate VG01 :

vgchange -a y vg01
vgchange: Warning: Couldn't attach to the volume group physical volume "/dev/dsk/c0t14d0":
The path of the physical volume refers to a device that does not
exist, or is not configured into the kernel.
vgchange: Warning: couldn't query physical volume "/dev/dsk/c0t15d0":
vgchange: Couldn't query the list of physical volumes.
vgchange: Couldn't activate volume group "vg01":
Quorum not present, or some physical volume(s) are missing.


I have this message for all disks of VG01.

thanks.

Hi,

it seams that the disks doesn't responce in the time LVM recommended it.

Please check if the disks are available:

# ioscan -fnCdisk

and grep for "/dev/dsk/c0t14d0" and "/dev/dsk/c0t15d0".

Please check also the timeout of the disks:

# pvdisplay -v /dev/dsk/c0t14d0 | grep -i timeout

# pvdisplay -v /dev/dsk/c0t15d0 | grep -i timeout

I know problems with disk in EMC where we have to increase the time. Perhaps you have to set it up to 180 (sec), see man 'pvchange'.

by any means did you change the SCSI id for any of the disks?

Please post the output of

#ioscan -fnC disk

#pvdisplay -v /dev/dsk/cxtydz
(for both the disks)

Also the output of /etc/lvmtab.

When i do an ( ioscan -fnC disk ) the devices c0t14d0 and c0t15d0 don't appears.
and when i do a pvdisplay it returns me this error, (it looks like disks do not exits) :

pvdisplay: Warning: couldn't query physical volume "/dev/dsk/c0t14d0":
The specified path does not correspond to physical volume attached to
this volume group
pvdisplay: Warning: couldn't query physical volume "/dev/dsk/c0t15d0":
The specified path does not correspond to physical volume attached to
this volume group
pvdisplay: Couldn't query the list of physical volumes.
pvdisplay: Couldn't retrieve the names of the physical volumes
belonging to volume group "/dev/vg01".
pvdisplay: Cannot display physical volume "/dev/dsk/c0t14d0".

Hi,

if a 'ioscan' didn't show the disk then it seams to be a hardware problem ;-(

Please open a harware case with your HP Responce Center.
