Notes:
The three-letter product codes are the first three letters of subset names. For example, a subset
named ATMBASExxx is part of the ATM product (Atom Advanced Developers Kit), which is
a blocking layered product. However, a subset named OSFATMBINxxx contains the letters
ATM, but the subset is not part of a blocking layered product; it is a subset in the OSF product
(the base operating system).
When a blocking layered product is removed as part of the rolling upgrade, it is removed for all
members. Any services that rely on the blocking product will not be available until the roll
completes and the blocking layered product is reinstalled.
Rolling Upgrade and RIS
When performing the install stage of a rolling upgrade, you can load the base operating system
subsets from a CD-ROM or from a Remote Installation Services (RIS) server.
Note:
You can use RIS only to load the base operating system subsets.
To use RIS, you must register both the lead member and the default cluster alias with the RIS
server. When registering for operating system software, you must provide a hardware address
for each host name. Therefore, you must create a hardware address for the default cluster alias
in order to register the alias with the RIS server. (RIS will reject an address that is already in
either of the RIS server's /etc/bootptab or /var/adm/ris/clients/risdb files.)
If your cluster uses the cluster alias virtual MAC (vMAC) feature, register that virtual hardware
address with the RIS server as the default cluster alias's hardware address. If your cluster does
not use the vMAC feature, you can still use the algorithm that is described in the vMAC section
of the Cluster Installation manual to manually create a hardware address for the default cluster
alias.
A vMAC address consists of a prefix (the default is AA:01) followed by the IP address of the
alias in hexadecimal format. For example, the default vMAC address for the default cluster alias
deli whose IP address is 16.140.112.209 is AA:01:10:8C:70:D1. The address is derived
in the following manner:
Default vMAC prefix: AA:01
Cluster Alias IP Address: 16.140.112.209
IP address in hex. format: 10.8C.70.D1
vMAC for this alias: AA:01:10:8C:70:D1
Another method for creating a hardware address is to append an arbitrary string of eight
hexadecimal numbers to the default vMAC prefix, AA:01. For example, AA:01:00:00:00:00.
Make sure that the address is unique within the area served by the RIS server. If you have more
than one cluster, remember to increment the arbitrary hexadecimal string when adding the next
alias. (The vMAC algorithm is useful because it creates an address that has a high probability of
being unique within your network.)
