Hardware Exclusion Guidelines
Hardware Element Exclusion Guidelines
IMPORTANT:
If the following hardware elements are excluded, the corresponding server domain will not
power up:
• Master IOC, Master IOC HubLink 1, Master IOC PCI Slots 1 & 2, Master IOL
Note:
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.
IOC • Slave IOCs can be safely excluded from a domain, but
connected peripherals will no longer be accessible.
• If the Master IOC is excluded from a domain, the domain
will not power up.
IOC HubLink • All IOC HubLinks not connected to a boot disk 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 (Master IOC boot disk)
HubLink_2 controls PCI slots 3 & 4
HubLink_3 controls PCI slots 5 & 6
Note:
If Master IOC HubLink_1 is excluded, the domain will not
power up.
PCI Slot • 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, system disks will
no longer be accessible and the domain will not power up.
IOL • Slave IOLs can be safely excluded from a domain, but
connected peripherals will no longer be accessible.
Note:
If the Master IOL is excluded, the domain will not power up.
DIB • A DIB can be safely excluded from a domain if it does not
house the boot disk.
• In Chained DIB configuration, if you exclude one DIB, the
other DIB will also be automatically excluded.
Note:
If a DIB housing a boot disk is excluded, the system disk will
no longer be accessible and the domain will not power up.
