Adding a Managed Volume
Allowing the Volume to Modify on Import
9-10 CLI Storage-Management Guide
Redundant directories are only a problem if their file attributes (such as their
permissions settings) do not match, or if they have the same name as an
already-imported file. Collided directories are renamed according to the same
convention as files.
You will have the option to disallow file renames and/or directory renames for
individual shares. These are discussed later in the share-configuration section.
From gbl-ns-vol mode, use the
modify command to allow the volume to modify
redundant files and/or directories on import:
modify
Clients cannot write to the volume until you run the
modify command.
The CLI prompts with a question about re-imports. The CLI Maintenance Guide
describes how to use a namespace-check tool (nsck) to re-import a previously-enabled
volume. This tool turns off the
modify setting and takes the volume offline. The
modify setting stays off during re-import unless you raise a flag by answering this
question. Answer “yes” to allow the modify setting to remain if the volume is rebuilt
through nsck.
For example, this command sequence allows the ‘/acct’ volume to modify files on
import and re-import.
bstnA6k(gbl)# namespace wwmed
bstnA6k(gbl-ns[wwmed])# volume /acct
bstnA6k(gbl-ns-vol[wwmed~/acct])# modify
Automatically re-enable volume modify mode during nsck rebuild? [yes/no] yes
bstnA6k(gbl-ns-vol[wwmed~/acct])# ...
Conditions for Running the modify Command
You can run the modify command
• before the volume is first enabled, or
For a multi-protocol (NFS and CIFS) namespace, directories are also renamed if their
CIFS names are not mappable to the NFS-character encoding. This was discussed in
“Setting NFS Character Encoding” on page 7-11.
