Page 13: General Description
The DS2500 is a dual-redundant Fibre Channel (FC) loop storage system used on systems running HP-UX operating system software. The DS2500 occupies 3 EIA units in a standard 19-inch rack. Up to 14 disk drives can be mounted in the front of the enclosure. Up to 4 DS2500s can be daisy-chained together to create a storage ring. -

Page 37: Note
Installing multiple disk drives HP recommends that you install a maximum of four disk drives at one time. If you need to install more than four drives in an operational system, complete the procedure for each of the four disks (one at a time), and then repeat it for another set of four until all drives have been added. - Page 38 If the drive continues to fail after two reseats, it may be defective. Try another drive. When all of the drives you inserted in Step 1 have displayed a solid green ready indicator for at least 10 seconds, you can repeat this procedure with another set of up to four drives. When all drives have been inserted, verify the addition of the new drives (see "Verifying the installation"...
