SEVM Issues
If you want to build your SEVM volumes on top of AP, you should configure your
volumes using AP metadisk paths rather than physical paths. SEVM recognizes and
properly installs existing AP metadevices with no special action required.
SEVM can encapsulate both nonboot disks and boot disks that are configured as AP
metadevices. SEVM can encapsulate AP databases without any impact on AP. Note,
however, that the standard SEVM requirements for encapsulation apply:
■
There must be an
s2
slice that represents the entire disk.
■
There must be a "small amount" of free disk space at the beginning or end of
the disk.
■
There must be two free partitions.
The partition requirement may necessitate giving up an AP database, which is
often placed in slice
s4
.
It is best to configure SEVM after you configure AP. It is beyond the scope of this
document to describe how to integrate AP with an existing SEVM configuration.

SDS Issues
If you want to build your SDS volumes on top of AP, you should configure your
volumes using AP metadisk paths rather than physical paths. SDS recognizes and
properly installs existing AP metadevices with no special action required.
6. Reboot the domain (if necessary).
If you just rebooted the domain after configuring a volume manager, this step is
unnecessary.
Performing an Upgrade of AP
This section provides upgrade instructions for AP 2.2 on the SSP and on a domain.
AP 2.0 and AP 2.1 are not supported under the Solaris 7 8/99 operating
environment. The upgrade process involves removing the earlier version of AP on
the SSP and on the host domain, installing one AP package on the SSP and a set of
core AP packages on the domain, and restoring your AP configuration. Scripts are
provided to simplify this process.
Caution –
If you are installing AP 2.2 on a Sun Enterprise 10000 domain, the SSP
must be running the SSP 3.1 software. SSP 3.0 does not support AP 2.2. Refer to your
SSP Media Kit for instructions on how to install the SSP software.
