HP-UX vPars and Integrity VM V6.3 Administrator Guide

Maximum memory : 6144 MB
Current memory : 2103 MB
Comfortable minimum : 27 MB
Boot memory : 6135 MB
Free memory : 0 MB
Available memory : 286 MB
Memory pressure : 100
Memory chunksize : 65536 KB
Driver Mode(s) : STARTED ENABLED
.
.
.
An indication of this problem is a small or zero amount of free memory and a large memory
pressure value (100). If these indicators are present, use the hpvmmodify command on the VSP
to increase the memory size of the VM. The VM then boots normally.
13.14.3.4 Actual memory allocations
If you specify a value for the ram_target or ram_dyn_target_start parameter that results
in a change in memory size that is not a multiple of 64 MB, the target value is reset.
For example, if you specify 6 GB of memory, the HP-UX guest actually has access to 6135 MB of
memory. If you attempt to set the memory size to 2048 MB, the amount of memory actually removed
is 4087 MB. This is not a multiple of 64 MB, so the target memory size is reset to 2103 MB.
13.14.3.5 Enabling dynamic memory on the VM and on the VSP
The VirtualBase software must be installed on the VM before you can use dynamic memory
parameters on the VSP system. For example, if the VirtualBase software is not installed, the
hpvmstatus command displays the following:
# hpvmstatus -V -P host1
.
.
.
[Dynamic Memory Information]
NOTE: Dynamic data unavailable, configured values only
Type : driver
Minimum memory : 1024 MB
Target memory : 2048 MB
Maximum memory : 3072 MB
.
.
.
If you attempt to modify the dynamic memory of the VM from the VSP, the following errors are
displayed:
# hpvmmodify -x ram_target=2048M -P host1
hpvmmodify: ERROR (host1): Query to dynamic memory driver failed: Function is not available.
hpvmmodify: Failed to set ram_target.
hpvmmodify: Unable to modify the guest.
If you attempt to modify the dynamic memory from the VM, the following errors occur:
# hpvmmgmt -V -l ram
Dynamic memory driver not found on guest.
hpvmmgmt: Unable to continue.
# hpvmmgmt -x ram_target=2048
Failed to open dynamic memory driver, error: No such device.
Failed to set dynamic value error: No such device
hpvmmgmt: Unable to continue.
For information about installing the VirtualBase software, see Section 2.6.2 (page 35).
