Hello Experts,<br />
<br />
&nbsp; I have two Sun Enterprise &nbsp;250 Server one with Sun OS 5.7 and the other with Sun OS 5.9. &nbsp;I was able to successfully mount another SCSI HDD to the OS 5.7 , I formatted the disk and mounted it with no problems. However I need the server with Sun OS 5.9 to have that hard drive space for some Oracle installaion. So, I took out the SCSI HDD from Sun OS 5.7 and put on Sun OS 5.9 and did a format command and i'm unable to see the drive. These are the exact same servers except for the version os OS. Not sure why OS 5.9 is not seeing the SCSI drive.

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
