First of all, it's bad practice to put NFS mounts in /etc/fstab
Use automount rather.

Why ? Cause network issues or nfs server issue can cause your entire machine to hang on boot.

For your problems actions you can take is :
0. Check NFS server. Problems related are probably due to misconfiguration on server for your client.
1. Use lsof with grep to identify which process are being used on sv55adm, to kill them
2. fuser -cku /mountpoint
3. If everything else fails, stop nfs client and umount (other nfs mountpoints will also stop working.)

You can also use bdf -t vxfs to display just vxfs filesystems before issue is resolved.

automountd(1M)															    automountd(1M)

NAME
automountd - autofs mount/unmount daemon SYNOPSIS
automountd [-Tvn] [-D name=value] automountd is an RPC server that answers file system mount and unmount requests from the autofs file system. It uses local files or name service maps to locate file systems to be mounted. These maps are described with the automount(1M) command. If automount finds any non-trivial entries in either the local or distributed automount maps and if the daemon is not running already, the automountd daemon is automatically invoked by automount(1M). automountd enables the svc:/network/nfs/nlockmgr service (lockd(1M)), and the svc:/network/nfs/status service (statd(1M)), if NFS mounts need to be done. At startup, the automountd daemon is invoked as is invoked as the system/filesystem/autofs:default service. See . The following options are supported: -D name=value Assign value to the indicated automount map substitution variable. These assignments cannot be used to substitute variables in the master map auto_master. -n Turn off browsing for all autofs mount points. This option overrides the -browse autofs map option on the local host. -T Trace. Expand each RPC call and display it on the standard output. -v Verbose. Log status messages to the console. USAGE
See largefile(5) for the description of the behavior of automountd when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes). /etc/auto_master Master map for automounter. /etc/default/autofs Supplies default values for parameters for automount and automountd. See autofs(4). See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ svcs(1), automount(1M), svcadm(1M), autofs(4), attributes(5), largefile(5), smf(5) The automountd service is managed by the service management facility, smf(5), under the service identifier: svc:/system/filesystem/autofs Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser- vice's status can be queried using svcs(1). If it is disabled, it is enabled by automount(1M) unless the application/auto_enable property is set to false. 3 Mar 2005 automountd(1M)
