Hi Alex,
See below for some high level stuff.
Majority of Unix flavors support doing most of the storage activity be done online without causing outage.
HPUX 11v2 and later are bundled with Veritas Vol. Mgr. So, no HP -LVM.
HPUX 11v1 and older. HP-LVM, resize only possible with Online JFS. Other Volume need to be offline to perform resize.
Solaris 10 update 3 and later- bundled with zfs. Pretty stable with update 8. DMP available with MPxIO and zpools only can be grown. native shrink option not available. LUN discovery doesn't require outage in most cases.
Solaris 9 bundled with SVM. resize to grow NOT shrink. LUN discovery with certain HBA's and certain configuration may require outage.
Solaris 8 SVM and some legacy slices. resize to grow NOT shrink with SVM. slices out of question. LUN discovery with certain HBA's and certain configuration may require outage.
AIX 5. AIX-LVM. resize doesn't require outage in most cases.
Linux RHEL - Native LVM, similar to HP-LVM. discovery and lun removal can be done online. resize depends on type of filesystem.
