HP 9000 Containers A.03.01 on HP Integrity Server Administrator Guide HP-UX 11i v3 (5900-3112, June 2013)

8.5.1 Configuring NFS and Autofs clients

HP 9000 system container

NFS and Autofs are supported inside an HP 9000 system container. Therefore, you can configure

them inside the container file system just the way you do it on the HP 9000 server.

HP 9000 classic container

NFS and Autofs are not supported inside an HP 9000 classic container. You can configure them

on the host system and then expose it to the container.

Configure /etc/fstab, /etc/auto_master, and /etc/auto.direct files on the host.

Perform actual mounts on the host system. Make the mount point visible inside the HP 9000 classic

container using the following command:

$ /opt/HP9000-Containers/bin/hp9000_link_dir \

8.5.2 Configuring VxFS mount points

HP 9000 system container

To configure VxFS mounts with HP 9000 system containers, the following options are available:

Configure pre-start mounts

Pre-start mounts are done from the global to the container file system when the container starts up.

They get unmounted when the container shuts down. The configuration must be done in /var/

hpsrp/<srp_name>.setup/fstab using the same format used in the host /etc/fstab. For

example,

$ echo “\n/dev/vg01/lvol2 /var/hpsrp/mysrp/mnt vxfs \

delaylog 0 2” >>/var/hpsrp/mysrp.setup/fstab

Configure container local mounts

Make the logical volume visible inside the container and configure the mount in the local fstab.

For example,

$ srp –add <srp_name> -tune device=/dev/vg01/lvol2

$ srp –add <srp_name> -tune device=/dev/vg01/rlvol2

$ echo “\n/dev/vg01/lvol2 /mnt vxfs delaylog 0 2\

>>/var/hpsrp/mysrp/etc/fstab

This facility is not currently supported for the /usr file system because the container has to do

LOFS mount of /usr/lib/hpux32 and /usr/lib/hpux64 before it can start any service. It is

not supported for /var too because container startup needs to read this directory.

Configure the mount on the HP-UX 11i v3 host

Configure the mount on the HP-UX 11i v3 host with the mount point inside the container. For

example, if there is a /mnt mount point on the HP 9000 server, configure the following:

$ echo “\n/dev/vg01/lvol2 /var/hpsrp/mysrp/mnt vxfs \

delaylog 0 2” >> /etc/fstab

Currently, there is a known limitation with this option. After system reboot, the bdf and mount

commands inside the container do not display information for these mount points. The issue is

related to RC sequencing order between fstab processing and SRP initialization, and does not

have an immediate fix. Hence, HP recommends using either the container pre-start fstab or

container local fstab file for configuring mounts.

Global mounts can be configured in SG packages (if required) without encountering the issue

mentioned above. This is because the SRP initialization completes before SG performs the mounts.
