HP-UX Virtual Partitions 6.0 Release Notes

Table 5 Known behaviors in vPars v6.0 (continued)
Description / actionProblem
Frequent interrupt migration on the vPar can lead to storage LUNs going offline.
This can occur indirectly when dynamic CPU migration occurs on a frequent
basis when the interrupt balancing daemon is enabled.
Interrupt balancing daemon is
disabled in vPars v6.0
What to do
The interrupt balancing daemon is disabled by default. Do not enable the
interrupt balancing daemon.
Because the base page size of host is set to 64K, the following commands might show incorrect results:
• acctcom
• acctcms
• acctprc2
These commands show incorrect values for mean memory size and kcore-minutes when the base page size is altered
to any value other than 4K. In order to see the correct value, the value should be multiplied by (base page size / 4K).
Example 4 Base page size= 64K
# /usr/sbin/acct/acctcom -mk mypacct3
COMMAND START END REAL CPU MEAN KCORE
NAME USER TTYNAME TIME TIME (SECS) (SECS) SIZE(K) MIN
#accton root pts/ta 15:42:33 15:42:33 0.01 0.01 0.00 0.00

dd root pts/ta 15:42:33 15:42:33 0.07 0.08 120.00 0.16

The actual value for KCORE-MIN will become (0.08 * (64/4)). The actual value for MEAN SIZE will become (120 *
(64/4)).
# /usr/sbin/acct/acctcms -a mypacct3
