Hello, all. My storage admin presented serveral LUNs to me, but for some reason one of them is showing up as being an empty disk. When I run the 'inq' command, I get the following:
/dev/rhdiskpower11 :DGC : RAID 5 : 0430 :APM00104 : -----
I've tried removing rmdev -Rdl and adding it back by cfgmgr, but I get the same results. Has anyone else run across this? I chatted with EMC support whose only recommendation was to remove everything PowerPath and reinstall. He based this on the fact that an lsattr -El shows both reserve_lock and reserve_policy options, which he said is wrong. His fix, though, seems a little overkill to me so I want to make sure I exhaust all possible avenues before going this route.
My System Info:
VIOS 220.127.116.11-FP24 SP-02
EMC powermt for PowerPath (c) Version 5.5 P 02 (build 3)
Thanks in advance for your help.
I see this quite often and it is the result of having an incorrect reserve setting
The other times I see this is when the device is a CLARiiON/VNX/Unity, VPLEX lunz, XIO SACD or Symm/VMAX ACLX
Which are all devices that allow communication to the array before actual luns are presented and are not real IO devices so will return ------ as the capacity.
What does 'lsdev -Cc disk' report this device as?
Does lsattr -El hdiskXX report the lun_id to be?
It may seem heavy handed to remove and reinstall but having both reserve lock and reserve policy will cause multiple problems and the way around this is a full uninstall/reinstall 5.5 is also well past end of life and should be upgraded.
