Operating Systems Solaris Can I create virtual disk from zpool on Solaris 11.4 for OVM? Post 303045100 by Peasant on Thursday 12th of March 2020 12:03:48 AM

Lets start with how many disks do you have in that box and what size ?
Did the operating system come install over entire devices (s2) ?
Can you show zpool status rpool on that box.

You have 3 choices for disks to use in ldoms :

1.) Reinstall the hypervisor on slice not entire disk, partitioning it in text installer and using VTOC label.
OR detach one of mirror disks, repartition with slice 0, attach. This will require that you have free space in rpool for such actions.
Then the other disk s0 after rebuild/resilver is complete - be sure to check eeprom and primary domain for boot device specification.
Reboot the server to confirm everything is ok.

After that, 2 x slice 0 (s0) will make rpool zpool, and all other slices (except s2!) can be used in ldoms after partitioning via format with free space.

Example, you have 2 x 300 GB, with slice 0 (s0) of 100 GB on each disk. You install operating system on it or repartition, attach, detach.
You are left with s1 to s6 (VTOC label, s2 excluded as it represents entire disk) to use with ldm add-vdsdev options=slice /dev/dsk/cNtNdNs1... on both disks.
Followed by a ldm add-vdisk id=<num> ... <ldom>
Add, for instance, s1 slices from both disks to ldom and create a mirrored rpool inside.

When you get SAN lun, you will add that lun to LDOM, and make a three way mirror of existing pool.
After the resilver is complete, you will detach and remove 2 local disks.
This would be mid level in terms on ease of setup.


2.) Creating ZVOL in existing zpool and adding /dev/zvol/dsk/ ... to LDOM.
Same with SAN lun afterwards, you add it, mirror and detach the old ZVOL after inside LDOM.
This will be worst performance, but easiest to setup on existing configuration.

3.) Combination of 1.) and SVM.
You mirror two slice 1 (s1) with all remaining space on SVM level and create soft partitions which you present to ldom as entire devices /dev/md/dsk..
Migration is done after the SAN lun is available to hypervisor via [/icode]meta..[/icode] commands on the hypervisor level or inside LDOM via zpool [attach|detach] commands.
This is the most complicated way and would advise against it if you do not have SVM experience.

No downtime is required for any operations above, unless, of course, you reinstall the hypervisor entirely.

Hope that helps

Peasant.

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
       installation media. Refer to the  for disk space requirements.

       Refer to the  for more information on the various menus and selections.
