I've ran a devfsadm -r on the boot disk before to move the system disk.But PowerPath is out-of-order by now. I would like at least he reinitialized its configuration to be now able to run but it says me : # powermt configUnexpected error occured.# powercf -qUnexpected error occurred.I've trie to rename /kernel/emcp.conf to another name, also to make devfsadm -C, to rename powercf.custom. Nothing works. Always the same problem.Any idea ?Regards 451Views Tags: none (add) support Content tagged with support , powerpath Content tagged with powerpath Categories: PowerPath 1. Re: "Unexpected error occured." error message (under Solaris) mack-xwWos Feb 1, 2007 9:15 AM (in response to Dakota) Dakota, I have had and seen similar issues with Power Path when moving devices etc around. It seems that Power Path gets upset and refuses to function properly. I'm not sure if some part of the config gets hung up or what it is. I have found that sometimes removing the Power Path package then re-installing it again clears up the issue. Not much help I know, but it has in the past worked for us. Good luck, mack Report Abuse Like Show 0 Likes (0) 2.

Removed the powerpath and installed it again, It required kernel rebuild and started http://muthu-t.blogspot.com/2011/02/powerpath-issue-on-hp-unix.html system reboot. But system was not able to boot. Below is the error faced.ERROR: phy_unit_init: Could not open file: /tmp/ign_configure/hw.info: No such file or directory (errno = 2)ERROR: read_hw_info failed The configuration process has incurred an error, would you like to push a shell for debugging purposes? (y/[n]):Solution:When initialization error powerpath software was uninstalled, it restored the pre-ignited image script to the startup files. This caused the server boot to fail checking for ignited configuration files in /tmp directory. The backup files are saved during the post-installation when the server is ignited. In general the files should not be powermt config unexpected altered but PP package removal seems to behave differently.The start scripts which were sourcing for ignited files were removed, rescanned the hardware, and the server was fully tested without PowerPath 5.1 installed.After validation, we installed Power Path 5.1learn:/sbin/rc2.d>swlist | grep -i emc EMCpower HP.5.1.SP2_b113 PowerPathAfter installation, the power path does not work as expected and behave the same way as the earlier versionlearn:/sbin/rc2.d>sh S999emcp startUnexpected error occured.emcpmgr: internal library error (0xebad002)Error: unable to update device configuration file(s)No migrations found.learn:/sbin/rc2.d>powermt display dev=allInitialization error.After numbers of attempts with remove/install PP, We finally found the main problem. It is actually a bug with PP and from versions like 4.x it is still there. What happened was that the entry in the /etc/inittab file for PP initialization which is running BEFORE the /sbin/init.d/emcp script and loads kernel modules to the host was missing on the host. /etc/inittab should ha
