After speaking to EMC about it, the root cause is usually either running out of space on the root filesystem or having the data and stack ulimit paramenters set too low after adding a large number of new LUNs.

Removed the powerpath and installed it again, It required kernel rebuild and started 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 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 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 have been updated during installation, but because that bug, it was not and PP kernel m
