Registered User

The lsof output just means it found something (a process, file, etc) in use by a user with the UID of 1002 but that user is not listed in the /etc/passwd file. I've seen this happen two different ways, there may be more. 1) The user started some processes and was removed from the system, but the processes continue to run. 2) The user is an NIS user and something has gone horribly wrong with NIS (but I think I have maybe only seen this once).

Let's back up a bit. Can you provide more info about the circumstances leading up to the LUN being removed? For example, are you scraping an Oracle instance that was running on the system and removed the LUNs and User ID? What SAN are you using?

If there is some event matching this type of scenario then I would be confident UID 1002 still has some processes running that are using that LUN.

In that case you can run 'ps -u 1002' or 'ps -U 1002' and see if you can identify the process or processes. You can then try to stop them gracefully, kill -HUP them, or kill -9 them.

If you have some other scenario where UID 1002 may not have anything to do with the issue, please give some details and we can try to tackle it a different way.

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
