PSM cache would increase the total size of all cache files (on all volumes
mounted to that point) above 1 TB, and an error message is written to the
system event log. The event source is psman5, and the text of the error
message is:
There is insufficient memory available.
– When a volume is failed over between nodes, then PSM running on the “new”
node will behave as it would if the volume were being mounted during a
restart: if that volume’s PSM cache would increase the total size of all cache
files on that node above 1 TB, then PSM blocks the mount and writes the
“insufficient memory available” error message to the system event log. (This
will also cause the failover to fail, which means that either the volume will try
to come online on the “original” node if it is up, or just simply fail to come
online at all.)
– If you increase the size of any cache such that the total cache size of all
volumes on the NAS Gateway 300 becomes greater than 1 TB, and if you do
not restart the NAS Gateway 300 after you change the cache size, then no
persistent images can be created on the volume for which the cache size
increase was made. An attempt to create a persistent image on that volume
will cause an error message to be written to the system event log. The event
source is psman5, and the text of the error message is:
There is insufficient memory available.
v If you delete the last persistent image on a volume, and then immediately
attempt to create a new persistent image on that volume, the creation of the new
persistent image might fail, and an error message will be written to the system
event log.
The event source is psman5, and the text of the error message is:
A persistent image could not be created due to error 0xc0000043.
This message is generated because when PSM is reinitializing the PSM cache
file on a particular volume (after you delete the last persistent image on that
volume), a new persistent image cannot be created. If this error occurs, wait for a
few minutes, and then try to create the persistent image again.
v
If you use the Windows Powered Disk Defragmenter to attempt to defragment a
volume containing persistent images, the volume will not be defragmented. If you
select the volume and click the
Defragment button, the Disk Defragmenter will
run on the volume and then indicate that the volume was successfully
defragmented. However, the Analysis display will appear the same as it did
before you clicked
Defragment , which indicates that defragmentation did not
take place. You can defragment volumes without persistent images.
v PSM uses several system level files, one of which has a command line interface.
Use of this interface is only supported for IBM-provided applications and
services, as well as IBM support technician assisted debugging efforts. All PSM
function including sophisticated scheduling and automation of remote
management is provided by the Windows 2000 for NAS Web-based GUI.
Attention: The recovery process invalidates persistent images and leaves them in
an inconsistent state. So, if you plan to use the Recovery CD-ROM, it is
recommended that you first delete all persistent images to ensure a clean reload of
the system software. For more information on using the Recovery CD-ROM, see
Chapter 9, “Using the Recovery and Supplementary CD-ROMs” on page 111.
