If it's SAN issue, you should check if multipath is configured for the mountpoint / disk[s] failing.
Perhaps administrator forgot to configure path, one of your FC cards died and it cannot see LUN(S) used for this mountpoint.Smilie

Also check clients, you would want to umount that share from all clients using broken NFS share.

Is there anything in syslog ?
Basicely, NFS issues are visible clearly in the client's syslog and disk problems should be on server's syslog.

Using open source solutions (or your scripts) you can parse those logs on multiple servers and create notifications and such (email, web or whatever).

nfsconfig(8)						      System Manager's Manual						      nfsconfig(8)

NAME
nfsconfig - Launches the SysMan Menu at the Network File System Configuration (NFS) level, where you can configure a system as an NFS server or as an NFS client SYNOPSIS
/usr/sbin/nfsconfig /usr/sbin/sysman nfs DESCRIPTION
The NFS Configuration section of SysMan Menu is used by the System Administrator or the UNIX system manager to manage NFS configuration issues. It allows the system to be configured as an NFS server (to make its file systems available to remote machines), or as an NFS client (to mount remote file systems). Before using nfsconfig, be sure to configure Network Interfaces using the Network Configuration section of the SysMan menu. You can configure your system as an NFS Server, an NFS Client, or both. However, if the Network Interfaces are down, the following daemons will not start: nfsd, pcnfsd, proplistd, mountd, and automountd. Use nfsconfig to do the following: Manage the configuration of the system as an NFS server. You can only configure your system as an NFS server if the NFS Server option is built into the kernel. Manage the configuration of the system as client-only system Specify file sys- tems to be mounted or exported Start and stop the NFS daemons Online Help: Online help is available for the NFS dialog boxes. You can get help by selecting the Help button on any dialog box. RESTRICTIONS
You must be root or have the appropriate privileges to run this application. FILES
Specifies the environment variables that define the nfsconfig configuration on your system SEE ALSO
Commands: X(1X), automount(8), mountd(8), nfsd(8), nfsiod(8), pcnfsd(8), proplistd(8), rpc.lockd(8), rpc.statd(8), dxfileshare(8) Files: nfs_intro(4), rc.config(8) Networking: tcp(7), udp(7) nfsconfig(8)
