Monitoring the Server
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.
QBB
•
At least one QBB must be “included” in a domain.
CPU
•
At least one CPU must be “included” in a QBB.
Note:
If all CPUs are excluded from a QBB, the QBB itself is
excluded.
SPS
•
At least one SPS must be “included” in a Core Unit.
Note:
MSX_0 SPS all CPUs are excluded from a QBB, the QBB itself
is excluded.
Clock
•
At least one Clock must be “included” in a Core Unit.
DPS Unit
•
Only one DPS unit can be safely excluded at a given time.
Fanbox
•
Only one Fanbox can be excluded from a domain at a given
time.
Note:
If more than one Fanbox is excluded, the domain may not
power up.
