odd entry in /etc/fstab
I was making text file copies of some system utility output (e.g. ioscan) and happened to look at /etc/fstab and found this:
Code:
/dev/vg02/lvol1 /prodbkup       vxfs    ioerror=mwdisable,log,nodatainlog,dev=40
020001  0       0

my other entries look like this:
Code:
/dev/vg04/lvol1 /trainbkup vxfs log,nodatainlog 0 0

I have no idea why this filesystem is different. tje ioerror=mwdisable and the dev=40020001
What does it mean and does it make sense?

LEARN ABOUT OPENSOLARIS

dev

dev(7FS)							   File Systems 							  dev(7FS)

NAME

       dev - Device name file system

DESCRIPTION

       The  dev  filesystem  manages  the  name  spaces  of devices under the Solaris operating environment. The global zone's instance of the dev
       filesystem is mounted during boot on /dev.

       A subdirectory under /dev may have unique operational semantics. Most of the common device names under /dev are	created  automatically	by
       devfsadm(1M).   Others,	such  as  /dev/pts,  are dynamic and reflect the operational state of the system. You can manually generate device
       names for newly attached hardware by invoking devfsadm(1M) or implicitly, by indirectly causing	a  lookup  or  readdir	operation  in  the
       filesystem to occur.  For example, you can discover a disk that was attached when the system was powered down (and generate a name for that
       device) by invoking format(1M)).

FILES

       /dev    Mount point for the /dev filesystem in the global zone.

SEE ALSO

       devfsadm(1M), format(1M), devfs(7FS)

NOTES

       The global /dev instance cannot be unmounted.
