HP Integrity BL870c Server-Blade - Manual (Page 41)

When scaling up, at least one monarch blade becomes an auxiliary blade. The profiles from the
monarch blades in the old Blade Link Domain are first unapplied from the old configuration. Then
the profiles assigned to the monarch blades of the nPartitions in the new configuration are applied
to those nPars. Any profile assigned to a bay that changed from monarch to auxiliary is now
considered to be assigned to a “Covered-Auxiliary” bay. It is still assigned to the bay, but not
applied to a server.
Consider the case where configuration of the current Blade Link Domain in bays 1-4 is AACC and
therefore there are two nPars, the AA nPar and the CC nPar. Profile Test1 is assigned to bay 1and
applied to nPar AA. Profile Test2 is assigned to bay 3 and applied to nPar CC. The configuration
of the Blade Link Domain is then changed to AAAA. Profile Test1 is first unapplied from nPar AA
and Profile Test2 in unapplied from nPar CC. Profile Test1 is then applied to the entire 4-blade
server. Profile Test2 is now assigned to a “Covered-Auxiliary” bay (bay 3).
Scaling down the size of an nPartition
Scaling down the size of an nPartition means the number of server blades in the nPar has decreased.
The possible scaling down of nPars are:
Table 10
nPar To nPar From
ABCD, AACD, ABCC, or AACC AAAA
ABCD, AACD, or ABCC AACC
ABCD AACD or ABCC
When scaling down, at least one auxiliary blade becomes a monarch blade. The profile assigned
to the monarch blade of the old nPar is first unapplied and then reapplied to the new nPar
configuration. The new monarch blade will have no profile assigned to it unless the bay was
considered to be a “Covered-Auxiliary” in the old Blade Link Domain configuration. The profile
from that bay would then be applied to the new nPar.
The current Blade Link Domain configuration in bays 1-4 is AAAA. Profile Test 1 is assigned to the
server and thus has been assigned to bay 1 and applied to bays 1-4. Profile Test2 is assigned to
Bay 3, and so would be shown as assigned to a “Covered-Auxiliary” bay. The Blade Link Domain
configuration is changed to AACD. Profile Test1 is now reapplied to the AA nPars (bays 1-2) and
profile Test 2 is applied to the C nPar (bay 3). Because bay 4 had no profile assigned to it, the
nPar D has no profile applied to it.
NOTE: In both of the previous examples, notice that the nPar changes AACD to ABCC and ABCC
to AACD would contain both a scaling up and a scaling down. In both cases, a dual-blade nPar
becomes two single blade nPars and two single-blade nPars become a dual-blade nPar.
