Well, sorry. Let's make it general then:

- How can I be sure the SAN disks accessible from the server are not being used by the OS?

- Imagine a "Solaris" global zone with few zones, each one with his own LUN. So when removing a zone, one have first to dettach the LUN in order to "free the resource" so it can be used to another purpose. Now the same situation with Linux and without zones: how can I be sure a SAN disk is not being used?

NAME
zcons - Zone console device driver DESCRIPTION
The zcons character driver exports the console for system zones. The driver is comprised of two "sides:" a master side with which applica- tions in the global zone communicate, and a slave side, which receives I/O from the master side. The slave side is available in the global zones. Applications must not depend on the location of /dev or /devices entries exported by zcons. Inside a zone, the zcons slave side is fronted by /dev/console and other console-related symbolic links, which are used by applications that expect to write to the system console. The zcons driver is Sun Private, and may change in future releases. FILES
/dev/zcons/<zonename>/masterconsole Global zone master side console for zone <zonename>. /dev/zcons/<zonename>/slaveconsole Global zone slave side console for zone <zonename>. /dev/zconsole Non-global zone console (slave side). ATTRIBUTES
