Red Hat Bugzilla – Bug 593241
RFE - Online LUN expansion not mentioned
Last modified: 2010-07-13 19:13:21 EDT
Description of problem:
Some Storage Arrays support the Online LUN expansion feature (for example HP EVA in a FC SAN Environment with Q-Logic and Emulex HBA's).
Unfortunately, this feature is not mentioned in the current Online Storage Reconfiguration Guide.
Question: is this feature supported with the current RHEL update release and if yes, why is it not documented in the above guide?
There is at least one other bugzilla Entry on this subject (https://bugzilla.redhat.com/show_bug.cgi?id=450992) that requesting the same feature.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Please document this feature if Oline LUN expansion it is indeed supported by RHEL 5.
Thanks Arnold. I'll get this documented as soon as I can confirm whether it's supported for any specific RHEL minor updates.
Does this help?
the link from Rob indeed points to the documetation of online resizing an FC LUN. - I must have overlooked it, sorry about that!
While I'm not sure wether the rescan has to be done on all physical paths, I think it dosn't have adverse effects either.
Thanks much for your speedy reply & best Regards,

The documentation indicates that each device needs to be re-scanned in section 14.1 under the 'important' message.
I hope this is helpful.
great! - I think you may close this "NOTABUG".
Thanks & Regards,
