i need to add 2 disks to an existing unit on the storage in raid 5 , i make the config directly from the console to the storage and add the 2 disks to the unit byb the commands EXPAND and EXTEND , the file syatem still the same size when i use the command DF -V on the tru64 server ,

Remember to take care based on the OS version!

From the AdvFS Admin Manual (http://h30097.www3.hp.com/docs/base_doc/DOCUMENTATION/V51B_HTML/ARH96DTE/TITLE.HTM)

2.3.4.3 Increasing Storage in Domains by Extending an Existing Volume:
You can increase the amount of storage available in your domain by enlarging the size of an existing volume. For example, LSM and hardware RAID controllers support dynamically increasing the size of a volume. Because expanding the size of an LSM or hardware RAID volume is done independently of AdvFS, you must notify the domain when the size of a volume changes by using the mount command with the -o extend option. You only need to mount one fileset with this option to increase the size of the domain.

If the fileset is not already mounted, enter:

mount -o extenddomain#fileset /mount_point

If the fileset is already mounted, enter:

mount -u -o extenddomain#fileset /mount_point

When the -o extend option is used, all additional storage is available to all filesets in the domain.

Yes, you DO need to run disklabel (last time we tested we did).

disklabel -rw dskX

Where X is the device number. The filesystem must be umounted to run disklabel sucessfully.

ok thank's , i will try that with disk label command but did this command destroy the data on the file system??

[Johan Brusche]

Be carefull if you have other partitions than the 'c' partition in use on that logical unit. Eg: if you have the d and e parition in use, you can only expand the filesystem on the e-partition without initializing the filesystem.

We did not loose data, you only reconfigure "the end of the disk", but take in account what Johan said.
