Operating Systems Solaris How to map device to mount point? Post 303024696 by Peasant on Monday 15th of October 2018 11:16:08 AM

Solaris 11 on x86 or SPARC ?
I'll presume it's SPARC as far as Oracle VM info goes ...

Try the following iostat command :
Code:
iostat -xcnzCTd 3 10

As manual states :
Code:
....
     -x          Report  extended  disk  statistics.  By  default, disks are
                   identified by instance names such as ssd23 or  md301.  Com-
                   bining the x option with the -n option causes disk names to
                   display in the cXtYdZsN format, more easily associated with
                   physical  hardware characteristics. Using the cXtYdZsN for-
                   mat is particularly helpful in  the  FibreChannel  environ-
                   ments where the FC World Wide Name appears in the t field.
...

Outside of yourldom, on the control/service domain which is hosting that disk service, you will need to match the disks added in virtual disk service (vds) and ID chosen when disk is added to yourldom
Code:
ldm add-vdisk id=N backend-disk backend-disk@some-vds yourldom

Where N above is the number you see for that specified disk inside ldom on iostat/format/zpool commands and the numeration of disk(s) you see when doing ldm list -l yourldom.

This assumes you are not using ZVOLs or metadevices as disk backends on control/service domain.
If you do, more stuff will need to be done to match the physical to virtual disk.

But ZVOL as disk backend to ldom and then vxfs while having zfs filesystem as well in ldom sounds like a nightmare....

For further analysis, i would required output of following command, which can be quite long so can attach them or something.

Code:
# On control/service domain 
ldm list-services
ldm list -l <yourldom>
ldm list
echo "::memstat" | mdb -k
tail -10 /etc/system
# On LDOM for start
echo | format

Hope that helps
Regards
Peasant.

NAME
halmount - mount and umount filesystems via hal SYNOPSIS
halmount [OPTIONS]... <device|label> [mountpoint] halmount -u [OPTIONS]... <device|label|mountpoint> halmount -e [OPTIONS]... <device|label|mountpoint> DESCRIPTION
halmount can mount and umount filesystems via hal. Hotpluggable devices and media such as USB sticks and CD-ROMs are typically not entered into /etc/fstab and are therefore not mountable by normal users via the mount(8) command. Instead hal provides methods to mount and umount such devices. Additionally it's also possible to eject devices. For devices like USB sticks eject means the device cannot be mounted again until the stick is re-plugged, ie a "save remove" feature. OPTIONS
-t TYPE specify the file system type to use -o OPTIONS specify mount options -v verbose listing of devices -u umount specified device -e umount and eject specified device -a perform requested mount/umount/eject operation all available devices --listudi list UDIs of devices, useful for debugging EXAMPLES
halmount list all mountable devices known to hal halmount /dev/hdc mount device hdc on default mount point (/media/volumelabel) halmount /dev/hdc cdrom mount device hdc on /media/cdrom halmount -u "Holiday Pictures" umount device that has the label "Holiday Pictures" SEE ALSO
mount(8), umount(8), eject(1), fstab(5) SUSE Linux November 2006 halmount(1)
