Veritas InfoScale™ 7.4.1 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/dsk/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

   • 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
