Re: LUNS are not visible with the latest created date
So if you already have, old files and its running the reboot wont help.
You can remove old device files[carefully], and run insf -eC disk
this would create new files.

Re: LUNS are not visible with the latest created date
so u can delete the below device files and run #insf -eC disk
it would create new device files and you would be able to use them again.

Re: LUNS are not visible with the latest created date
On our production server all the filesystems are configured under the package config file. So for these vdisks we have presented 7 fcs (production+secondary server)
But i have created the filesystem which is not configured in the cluster so that i just presented the 4 fcds related to this server.
Totally for this one is 4 fcds.
For removing of these special device files which option should i prefer.
#rmsf -H
or
#rmsf
kindly suggest me.

Re: LUNS are not visible with the latest created date
For the clustered filesystems we have 8fcds.
The one which i created is with 4 fcds. So in that case i should get 8 device files right?

Re: LUNS are not visible with the latest created date
there would not be any issue.
Just if you wane cross check do a pvdisplay on each path to make sure its not part of any VG so that u wont lose any data...
(hope u don have VxVM cause pvdisplay do not work on vxvm)
