Interesting Problem! 2 VIOs, One is problematic, assigning disks and resources from the other only

Hi,
Thanks for the reply
I just checked that there is Multipathing done on both the VIOs.
I assigned these two disks from the "working VIO" to 5 LPARS.
Now on running cfgmgr on some of the LPARs the disks are visible. lspath too shows them "enabled". But on the other 2 or 3 LPARs running lspath shows these two disks as "defined" and cfgmgr hangs.
I guess this has something to do with MPIO aka multipathing. I fail to understand why the second VIO is hangiing
So its 3 LPARs that are hanging at cfgmgr and the disks are in "defined" state when lspath is executed.
Regards

reboot
reboot(8) System Manager's Manual reboot(8) NAME
reboot - Restarts the machine SYNOPSIS
/usr/sbin/reboot [-dlnq] DESCRIPTION
When the system is running and multiple users are logged in, use the shutdown -r command to perform a reboot operation. If no users are logged in, use the reboot command. The reboot command normally stops all running processes, syncs the disks, logs the reboot, and writes a shutdown entry in the login accounting file, /var/adm/wtmp. The reboot command uses the sync call to synchronize the disks, and to perform other shutdown activities such as resynchronizing the hard- ware time-of-day clock. After these activities, the system reboots. By default, the system starts and the file systems are automatically checked. If the start-up activities are successful, the system comes up in the default run-level. You must have root privileges to use this command. Using the -n flag can result in file system damage. FLAGS
Generates a crash dump of the system before halting it. Can be used with any of the other flags. Does not log the reboot using syslog Does not sync the disks or log the reboot using syslog Performs a quick reboot without first shutting down running processes; does not log the reboot using syslog EXAMPLES
To enable the default reboot action, enter: reboot This command causes the system to stop all running processes, sync the disks, log the shutdown, and perform other routine shutdown and reboot activities. To shut down the system without logging the reboot, enter: reboot -l This command shuts down the system and performs all shutdown and reboot activities, except logging the shutdown. To reboot the system abruptly, enter: reboot -q This command reboots the system abruptly without shutting down running processes. FILES
Specifies the command path Specifies the login accounting file Specifies the path of the syslog daemon RELATED INFORMATION
Commands: fsck(8), halt(8), init(8), savecore(8) shutdown(8), syslogd(8) Functions: reboot(2), sync(2), syslog(3) delim off reboot(8)
