bdf,df,umount get hangs

Madhuchakaravar — Thu, 05 Apr 2012 07:49:25 GMT

VG has lost connectivity with the SAN.

we are not unable to umount or vgexport the VG.

df,bdf,umount, ls to particular mount point also hang.

how it can be recovered without rebooting and even after rebooting will it be solved.

>> VG has lost connectivity with the SAN.

You need to investigate why the server cannot longer access the (redundant) SAN - there must be a reason either on the switches or the array or somewhere between.
