This machine is no longer under HP hardware maintenance.<BR /><BR />Data redundancy has been lost in disk array on /dev/dsk/C4t0d0. Disk in slot B4 has failed.<BR /><BR />Active hot spare warning on /dev/rdsk/C4t0d0. Unallocated space is too small for active hot spare.<BR /><BR />The rebuild is currently at 62%. The array has 7 18.2 GB disks.<BR /><BR />Once I get the new disk from my vendor, how should I proceed to replace it? Is it really hot-swapable? Is it actually hands-off? I am new to this particular crisis, so I appreciate your responses very much.<BR /><BR />Thank you,<BR />Robb Thu, 17 Jul 2003 14:51:30 GMT https://community.hpe.com/t5/disk-enclosures/replace-disk-in-array-12h/m-p/3026567#M9139 Robb Bailey 2003-07-17T14:51:30Z https://community.hpe.com/t5/disk-enclosures/replace-disk-in-array-12h/m-p/3026568#M9140 If disk is failed by 12h (its led is yellow) then simply wait until rebuild will complete and remove bad disk and insert new one.
