Device file not found for /dev/vx/dsk/rootdg/varvol

[Santhosh.c]

Hi,
I am facing some issue on ignite backup.
Possible cause I am getting is given below.
#/opt/ignite/lbin/list_expander
ERROR: Cannot stat device file: /dev/vx/dsk/rootdg/varvol: No such file or directory (errno = 2). Check /etc/fstab for a bad
entry.

this is the /etc/fstab entry for /var
# grep /var /etc/fstab
/dev/vx/dsk/rootdg/varvol /var vxfs delaylog 0 2


I have checked the bdf of /var
# bdf /var
Filesystem kbytes used avail %used Mounted on
/dev/vx/dsk/rootdg/varvol
8388608 6403800 1977528 76% /var

But I could not see the device in the path.

HI Santhosh,

Have a look at both links.

http://forums11.itrc.hp.com/service/forums/questionanswer.do?threadId=1219488

http://seer.entsupport.symantec.com/docs/318359.htm

There should be backup of the VXVM diskgroup configuration in the /etc/vx/cbr/bk directory.

cd to the rootdg directory, grep the file as mentioned in Robert's case for '^vol ', 'node_bdev=', and 'node_cdev'.

Recreate all device files with mknod command and the major/minor number you have found in your grep command.

Regards,
Robert-Jan

Can tou check it exist in rdsk dev/vx/rdsk/rootdg/

you will have to create the block file and raw file is that too does not exist.

Now question arises...who has deleted it.
any clue you have for this.
