The /G Directory
The /G Directory
The /G directory provides OSS names for Guardian files on your local NonStop
S-series or NonStop NS-series node. Each Guardian filename has a corresponding
OSS name of the form /G/volume/subvolume/fileID, where volume,
subvolume, and fileID are case-insensitive; for example,
$SYSTEM.SYS00.CONFLIST becomes /G/system/sys00/conflist.
The /G directory itself is reserved for HP use. You cannot put anything in this directory.
You also cannot add a directory at the /G/volume level of the directory hierarchy.
If you add or delete files below the /G/volume level of this directory, you increase or
decrease the amount of disk space used. However, the increase or decrease affects
only the disk volumes that contain the Guardian files, which can be different from the
volumes that contain OSS files. Therefore, if users delete files from the /G directory,
they might not free space for OSS files and can lose files that they intended to keep.
The /G directory is described in more detail in Section 3, Understanding the OSS File
System.
The /E Directory
The /E directory provides OSS names for OSS and Guardian files on remote NonStop
S-series or NonStop NS-series nodes. Each remote filename has a corresponding
OSS name of the form:
•
/E/nodename/pathname for OSS files
•
/E/nodename/G/volume/subvolume/fileID for Guardian files
where nodename, volume, subvolume, and fileID are case-insensitive.
For example:
•
The OSS file /tmp/datafile on \NODE2 becomes /E/node2/tmp/datafile
•
The Guardian file $SYSTEM.SYS00.CONFLIST on \NODE2 becomes
/E/node2/G/system/sys00/conflist.
The /E directory itself is reserved for HP use. You cannot put anything in this directory.
If you add or delete Guardian files below the /G/volume level of this directory, you
increase or decrease the amount of disk space used on the corresponding NonStop
S-series or NonStop NS-series node. However, the increase or decrease affects only
the disk volumes that contain the Guardian files—which can be different from the
volumes that contain OSS files.
If you add or delete OSS files below the /nodename level of this directory, you
increase or decrease the amount of disk space used on the corresponding NonStop
S-series or NonStop NS-series node. However, the increase or decrease affects only
the disk volumes that contain the OSS files, which can be different from the volumes
that contain Guardian files.
