Tips and Features for Administrators
Limiting Access to Hardware Resources
As Customer Administrator, you can use the PAM software Exclusion / Inclusion function
to logically limit access to certain hardware resources, such as:
IOCs When a domain comprises more than one cell (therefore more than one
IOC), the Master IOC is the one hosting the boot disk. The other IOCs in
the domain are Slave IOCs.
Slave IOCs can be safely excluded from a domain, but connected
peripherals will no longer be accessible.
Note:
If the Master IOC is excluded, system disks will no longer be
accessible and the domain will not power up.
IOC HubLink s All IOC HubLinks can be safely excluded from a domain, but connected
peripherals will no longer be accessible.
IOC HubLinks are organized as follows:
HubLink_1 controls PCI Slots 1 & 2
HubLink_2 controls PCI slots 3 & 4
HubLink_3 controls PCI slots 5 & 6
PCI Slots All PCI slots not connected to a boot disk can be safely excluded from a
domain, but connected peripherals will no longer be accessible.
Note:
If Master IOC PCI Slots 1, 2 are excluded, external system disks will
no longer be accessible and the domain will not power up.
IOLs Slave IOLs can be safely excluded from a domain, but connected
peripherals will no longer be accessible.

Notes:
Hardware exclusion / inclusion is a hardware management function, not a domain
management function.
To be taken into account, exclusion / inclusion requires domain power OFF/ON.
