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 118) 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
