we have almost the same configuration on some clusters, resizing luns (storage DS8300) works without problems, I think even without cfgmgr on both vio and lpar, at least it's not necessary on the vio server
as gito said, dynamic resizing of hdisks that belong to a concurrent vg working in concurrent active or concurrent passive mode is not supported, so you need to at least bring the resource group down once
just could imagine the problem in conjunction with your ds4xxx storage and the drivers on the vio servers
we have clusters with 80+ concurrent pvs, imagine remapping of every single one (we have a script for this, but anyways..), that must be a bug, I would open an IBM ticket in your case

Hi,
Is there any advantage is making all my storage LUNS ( hdisk ) of uniform size. Currently the LUN's are having different size () eg: 50G / 60G / 75G etc ).
I am planning for a storage migration....so should i go for uniform lun size or with current LUN size pattern ?

lpsched(1M) System Administration Commands lpsched(1M)
NAME
lpsched - start the LP print service
SYNOPSIS
lpsched [-f num_filters] [-n num_notifiers] [-p fd_limit] [-r reserved_fds]
DESCRIPTION
The lpsched command starts or restarts the LP print service.
The lpshut command stops the LP print service. Printers that are restarted using lpsched reprint (in their entirety) print requests that
were stopped by lpshut. See lpshut(1M).
It is recommended that you start and stop the LP print service using svcadm(1M). See NOTES.
OPTIONS
The following options are supported:
-f num_filters Specifies the number of concurrent slow filters that may be run on a print server. A default value of 1 is used if
none is specified. Depending on server configuration, a value of 1 may cause printers to remain idle while there
are jobs queued to them.
-n num_notifiers Specifies the number of concurrent notification processes that can run on a print server. A default value of 1 is
used when none is specified.
-p fd_limit Specifies the file descriptor resource limit for the lpsched process. A default value of 4096 is used if none is
specified. On extremely large and active print servers, it may be necessary to increase this value.
-r reserved_fds Specifies the number of file descriptors that the scheduler reserves for internal communications under heavy load.
A default value of 2 is used when none is specified. It should not be necessary to modify this value unless
instructed to do so when troubleshooting problems under high load.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
non-zero An error occurred.
FILES
/var/spool/lp/* LP print queue.

NOTES
The lpsched service is managed by the service management facility, smf(5), under the service identifier:
svc:/application/print/server
Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser-
vice's status can be queried using the svcs(1) command.
