InfoScale™ 9.0 Virtualization Guide - Solaris

To configure a direct mount inside a non-global zone

1. Create a VxVM disk group and volume:

   • Create a VxVM disk group from a device:

     global# vxdg init data_dg c0t0d1

   • Create a volume from a disk group:

     global# vxassist -g data_dg make data_vol 5G

     For more information, see the Storage Foundation Administrator's Guide.

2. Create a zone:

   • Create a root directory for a zone local-zone and change its permission to 700:

     global# mkdir -p /zones/local-zone
     global# chmod 700 /zones/local-zone

   • On Solaris 11, configure a zone local-zone:

     global# zonecfg -z local-zone
     
     local-zone: No such zone configured
     Use `create' to begin configuring a new zone.
     
     zonecfg:local-zone> create         
     zonecfg:local-zone> set zonepath=/zones/local-zone
     zonecfg:local-zone> set ip-type=shared
     zonecfg:local-zone> add net
     zonecfg:local-zone:net> set physical=eri0
     zonecfg:local-zone:net> set address=192.168.5.59
     zonecfg:local-zone:net> end
     zonecfg:local-zone > verify
     zonecfg:local-zone > commit
     zonecfg:local-zone > exit

     The zone is in configured state.

   • Install the zone:

     global# zoneadm -z local-zone install

   • Login to the zone console to setup the zone from terminal 1:

     global# zlogin -C local-zone

   • Boot the zone from another terminal:

     global# zoneadm -z local-zone boot

   • Follow the steps on terminal 1 on the zone console to setup the zone.

     See the Oracle documentation for more information about creating a zone.

3. Add VxVM volumes to the zone configuration:

   • Check the zone status and halt the zone, if it is running:

     global# zoneadm list -cv
     ID NAME       STATUS   PATH           BRAND    IP
     0 global      running  /              native    shared
     2 local-zone  running  /zones/myzone  native    shared
     
     global# zoneadm -z myzone halt

   • Add the VxVM devices to the zone's configuration:

     global# zonecfg -z local-zone
     zonecfg:local-zone:fs> add device
     zonecfg:local-zone:fs> set match=/dev/vxportal
     zonecfg:local-zone:fs> end
     zonecfg:local-zone:fs> add device
     zonecfg:local-zone:fs> set match=/dev/fdd
     zonecfg:local-zone:fs> end
     zonecfg:local-zone:fs> add device
     zonecfg:local-zone:fs> set match=/dev/vx/rdsk/data_dg/data_vol
     zonecfg:local-zone:fs> end
     zonecfg:local-zone:fs> add device
     zonecfg:local-zone:fs> set match=/dev/vx/dsk/data_dg/data_vol
     zonecfg:local-zone:fs> end
     zonecfg:local-zone:fs> add fs
     zonecfg:local-zone:fs> set dir=/etc/vx/licenses/lic
     zonecfg:local-zone:fs> set special=/etc/vx/licenses/lic
     zonecfg:local-zone:fs> set type=lofs
     zonecfg:local-zone:fs> end
     zonecfg:local-zone> verify
     zonecfg:local-zone> commit
     zonecfg:local-zone> exit

   • On Solaris 11, you must set fs-allowed to vxfs and odm in the zone's configuration:

     global# zonecfg -z myzone
     zonecfg:myzone> set fs-allowed=vxfs,odm
     zonecfg:myzone> commit
     zonecfg:myzone> exit

     See Adding a direct mount to a zone's configuration.

     See Mounting VxFS as VxFS inside a non-global zone.

   • Boot the zone:

     global# zoneadm -z myzone boot

4. Create a VxFS file system on the volume inside a non-global zone:

   • Login to the local-zone:

     global# zlogin myzone

   • Create a VxFS file system on the block device:

     bash-3.00# mkfs -F vxfs /dev/vx/rdsk/data_dg/data_vol

5. Create a mount point inside the zone:

   • Login to the local-zone:

     global# zlogin myzone

   • Create a mount point inside the non-global zone:

     bash-3.00# mkdir -p /mydata

   • Mount the VxFS file system on the mount point:

     bash-3.00# mount -F vxfs /dev/vx/dsk/data_dg/data_vol /mydata

6. Configure the zone service group:

   • On the first node, create the service group with password-less communication with global zone:

     global# hazonesetup -g zone_grp -r zone_res -z myzone \
     -p password -s sysA,sysB

     In case of non-secure clusters, if the security key is missing from the cluster configuration, an error occurs, which indicates that the secinfo value is missing. To generate the required security information for non-secure clusters, run the vcsencrypt -gensecinfo command.

   • Switch the service group from the first node to the second node and run the hazonesetup command to setup password-less communication from the next node.

   • Repeat step 6 for all the nodes in the cluster where the zone can go online.

   See Configuring a zone resource in a failover service group with the hazonesetup utility.

7. Create a mount, disk group, and volume resources into the service group:

   • Add a disk group resource to the service group:

     global# hares -add dg_res DiskGroup zone_grp
     global# hares -modify dg_res DiskGroup data_dg
     global# hares -modify dg_res Enabled 1

   • Add a volume resource to the service group:

     global# hares -add vol_res Volume zone_grp
     global# hares -modify vol_res Volume data_vol
     global# hares -modify vol_res DiskGroup data_dg
     global# hares -modify vol_res Enabled 1

   • Add a Mount resource to the service group:

     global# hares -add mnt_res Mount zone_grp
     global# hares -modify mnt_res BlockDevice \
     /dev/vx/dsk/data_dg/data_vol
     global# hares -modify mnt_res MountPoint /mydata
     global# hares -modify mnt_res FSType vxfs
     global# hares -modify mnt_res FsckOpt %-y
     global# hares -modify mnt_res Enabled 1

   • Create a resource dependency between the resources in the service group:

     global# hares -link zone_res vol_res
     global# hares -link vol_res dg_res
     global# hares -link mnt_res zone_res

8. Set the ContainerOpts attribute for the Mount resource for VxFS direct mount:

   • Override the ContainerOpts attribute at the resource level for mnt_res:

     global# hares -override mnt_res ContainerOpts

   • Set the value of the RunInContainer key to 1:

     global# hares -modify mnt_res ContainerOpts RunInContainer \
     1 PassCInfo 0

   For information on overriding resource type static attributes: see the Cluster Server Administrator's Guide.
9. Here is a sample configuration for the VxFS direct mount service groups in the main.cf file:

   group zone_grp (
          SystemList = {sysA = 0, sysB = 1 }
          ContainerInfo = { Name = local-zone, Type = Zone, 
   							Enabled = 1 }
          Administrators = { z_zoneres_sysA, z_zoneres_sysB }
           )
           
          Mount mnt_res (
                   BlockDevice = "/dev/vx/dsk/data_dg/data_vol"
                   MountPoint = "/mydata"
                   FSType = vxfs
                   FsckOpt = "-y"
                   ContainerOpts = { RunInContainer = 1, 
   																PassCInfo = 0 }
                    )
                                  
          DiskGroup dg_res (
                   DiskGroup = data_dg
           )
   
          Volume vol_res (
                   Volume = data_vol
                   DiskGroup = data_dg
           )
                                 
          Zone zone_res (
           )
   
          zone_res requires vol_res
          vol_res requires dg_res 
          mnt_res requires zone_res
