Boot Time Compliance
A compliance check is performed whenever a virtual partition is booted. If the total number of
cores assigned to all virtual partitions in the current vPar database exceeds the nPartition’s
intended active core count, the Instant Capacity software notifies the vPar monitor. The monitor
prevents any virtual partition from booting until the user first performs a hard partition boot
and then modifies either the vPar configuration or the Instant Capacity intended active count
for the nPartition. Example 4-7 shows a sample boot-time compliance message sent when a
virtual partition is prevented from booting.
Example 4-7 vPar Boot–Time Compliance Message
To: [e-mail]
Subject: vPar Boot Time Compliance
This message is being sent to inform you that a vpar is not
being allowed to boot because doing so would take this complex
out of compliance from an Instant Capacity perspective. The
number of cores assigned to this vPar database (/stand/vpdb)
exceeds the number of intended active cores by 1. To correct
this problem, boot this partition back into an nPartition and
modify the vPars assigned to this database or modify the number
of intended active cores for this nPartition.
