Restoring data on the storage unit when attaching multiple RS/6000 or
pSeries host systems to the storage unit
You can restore data on the storage unit when attaching multiple RS/6000 or
pSeries host systems to the storage unit.
This procedure assumes that you have preserved the data by following the
instructions in "Saving data on the storage unit when attaching multiple RS/6000 or
pSeries host systems to the storage unit" on page 81.
1. Check to be sure that the storage unit physical volumes (hdisks) are available.
2. Type importvg xxxx where xxxx is the name of the volume group to restore the
3. Type smit chvg to verify that No is selected for the Activate Volume Group
4. Type varyonvg VGname to vary-on the storage unit volume groups to the
5. Type mount to mount the storage unit volume groups to the applicable host
6. If you want to create new volume groups, go to step 3 in "Restoring data on the

Running the Linux operating system on an IBM pSeries host

This section describes how to attach a pSeries host system running the Linux
operating system with a fibre-channel adapter.
Attachment considerations for running the Linux operating system on
an IBM pSeries host
A pSeries host supports the Subsystem Device Driver (SDD) when using the Linux
operating system. The following sections provide information that you need to
prepare your system for SDD. You can also find instructions to install and verify
SDD.
Storage unit attachment is supported either by directly attaching a storage unit port
to the host adapter, or by attaching through a fibre-channel switch. You must specify
the proper attachment topology using the storage specialist. Select Loop to indicate
direct attachment.
Disabling automatic system updates
Many Linux distributions give an administrator the ability to configure their systems
for automatic system updates. Red Hat provides this in the form of a program called
up2date, while SUSE provides it as YaST Online Update. These features
periodically query for updates that are available for each host, and can be
configured to automatically install any new updates that it finds. This often includes
updates to the kernel.
