Reinstalling Instant Capacity Software
Preserving current Instant Capacity information
If you reinstall HP-UX on a partition with Instant Capacity (for example, installing HP-UX by either
cold-installing or installing from a golden image), you must perform the following steps. Otherwise,
all information in the Instant Capacity configuration file (change history, system contact information)
is lost.
IMPORTANT: If the system is a member of a GiCAP group, it should be removed from the group
before reinstalling HP-UX, and added back into the group after the reinstallation. “Reinstalling a
Group Member” (page 82) describes a workaround if HP-UX is reinstalled while a system is a
member of a GiCAP group. If the system is a GiCAP Group Manager, additional steps described
in Chapter 7 are necessary to configure the Group Manager after a reinstallation of HP-UX.
1. Before the reinstall action , manually save your Instant Capacity data and processor allocation
history by backing up the following files:
a. HP-UX: /etc/.iCOD_data
OpenVMS: SYS$SYSTEM:SYS$ICAP.DAT
b. HP-UX: /var/adm/icap.log
OpenVMS: SYS$MANAGER:ICAP.LOG
c. HP-UX: /var/adm/icap.log.old
d. OpenVMS: SYS$MANAGER:ICAP$CORES.DAT
These files are restored in step 3.
2. Install the appropriate HP-UX or OpenVMS OE from its media onto the partition. The Instant
Capacity software bundle B9073BA is installed automatically when the HP-UX OE is installed,
and the Instant Capacity software bundle BA484AA is installed automatically on OpenVMS
systems.
3. Restore your Instant Capacity data and processor allocation history files:
a. HP-UX: /etc/.iCOD_data
OpenVMS: SYS$SYSTEM:SYS$ICAP.DAT
b. HP-UX: /var/adm/icap.log
OpenVMS: SYS$MANAGER:ICAP.LOG
c. HP-UX: /var/adm/icap.log.old
d. OpenVMS: SYS$MANAGER:ICAP$CORES.DAT
Removing Instant Capacity Software
IMPORTANT: Do not attempt to remove the Instant Capacity software.
