emcpower device links do not exist in /dev/dsk and /dev/rdsk on Solaris 9

Question

Hi I have a Solaris Sun Fire 25K on Solaris 9(powerpath 5.2.2), I was checking the server today and i found that the emcpower device links do not exist in /dev/dsk and /dev/rdsk on Solaris 9, i ran the inq command and there are no emcpower devices; i checked these paths and those are empty, i dont no why, those devices are deleted. /dev/dsk/emc* /dev/rdsk/emc* /devices/pseudo/emc*blk /devices/pseudo/emc*raw but i am worried about it due if a run the powermt display i got this output: powermt displaySymmetrix logical device count=146CLARiiON logical device count=0Hitachi logical device count=0Invista logical device count=0HP xp logical device count=0Ess logical device count=0HP HSx logical device count=0==============================================================================----- Host Bus Adapters ---------  ------ I/O Paths -----  ------ Stats ------###  HW Path                       Summary   Total   Dead  IO/Sec Q-IOs Errors==============================================================================3075 pci@dc,600000/SUNW,qlc@1/fp@0,0  optimal      146      0       -     0      03076 pci@dd,600000/SUNW,qlc@1/fp@0,0  optimal      146      0       -     0      0 but there are no devices power what is happening? i ran the devfsadm command after that i ran the powercf -q but when i ran this command i got this error powercf -q Unexpected error occurred. Could you help me please, i think that if a perform a reboot with reconfiguration it is going to fix the issue(reboot -- -r)  but i want to know if i need to do something before the reboot, perhaps to move the emcp.conf or move the power.custom or only if i perform the reboot -- -r it is going to fix it Best regards

You are correct, a reconfigure reboot rebuilds the device special files. There is notthing you should need to do powerpath wise before the reboot.

You may consider deleting all non-boot disk device speccial files (relating to SAN disk) just to let them all rebuild from scratch.

After the reboot whe it's all ok and Powerpath commands are working again, do a 'powermt save'

You might find Knowledgebase article emc133499 useful, though its for scanning in new devices when using the leadville driver.
