The September fixes have changes for the zhcp log rotation. It will 
rotate, compress and then limit how many you will have. That should help. 

A future item is to also send out a warning message (using an hourly cron 
check) to the notify userid or operator as the disks are filling up.

Hi Chuck,
 
Thanks for the hint, I wasn’t sure where to look, but when I looked around 
on the zhcp node via the GUI, I finally saw that both /var/log/messages 
and /var/log/secure were very large.  After I emptied /var/log/secure 
(“cat /dev/null > /var/log/secure”), I was then able to see the expected 
disk pools in the z/VM Resources page and resume normal XCAT GUI usage. 
Note that this is only a Proof of Concept, so emptying this file is OK. 
 
I will take your advice about getting the service though, as I also 
noticed that some missing service may help with log rotation, perhaps even 
with this specific error. 
 
It seems that perhaps more attention is required to the zhcp filesystems, 
especially monitoring them for fullness.  Presumably it is common to 
automate this, which I’ll investigate.  Is there anything specific to 
avoid when manipulating the /var/log files for zhcp?  It seems possible to 
do it while the server is running, but my method here is potentially 
disruptive and I would prefer a “safe” method if there is one.
 
kind regards,
Peter

The code first looks to see if a file on the zhcp is newer than 5 minutes, 

and it will use that; otherwise it will call SMAPI to get the information. 

 
 
There may be something else off, maybe the zhcp is getting low on space to 

create the information. Are you at the latest service level? There are 
some exits described in the SMAPI book that you can use to clean out space 

on zhcp and xcat startup.

Subject: z/VM disk pool question
 
Hi,
 
For some reason the XCAT GUI no longer sees any disk pools on my z/VM 
system, when there are some to see.  How do I get it to rebuild its disk 
pool table?
 
I ask as when I view the Provision->z/VM Resources->Disks page in the GUI, 
it says:  “Below are disks that are defined in the EXTENT CONTROL file.” 
and shows an empty table:
 
No data available in table
 
I’ve bounced VSMGUARD and XCAT a couple of times, to no avail.  Is there 
something else I need to do?  I sees the networks OK on the same page:
Querying 1 zhcp(s) for networks.

Querying networks from: zhcp (1 of 1)
 
…lots of network table data snipped for the DTCSMAPI, XCATVSW1 and 
XCATVSW2 networks…
 
Showing 1 to 3 of 3 entries
 
Here is the z/VM view of the disk pools, the one I’m looking for XCAT to 
use for the Linux VMs is called GRPLNX:
