ETERNUS2000 Disk storage systems Server Connection Guide (SAS) for Linux
LUN Recognition
Procedure
When the driver installation process is complete, shut down the OS and turn the
server power off.
Turn the ETERNUS Disk storage system power off.
Use the SAS cables to connect the Linux server to the ETERNUS Disk storage
system.
Turn the ETERNUS Disk storage system back on.
Turn the server power back on and boot the OS.
Check that the Linux server recognizes the ETERNUS Disk storage system LUNs.
At boot up, Linux automatically recognizes all SCSI disks and assigns them successive
device names starting from "sda". When assigning the device names, any internal SCSI
disks are assigned first, followed by the assignment of the ETERNUS Disk storage
systems' LUNs. Example: If there is one internal SCSI disk, it is assigned a SCSI device
name as follows:
SCSI device name
by-id name (Example)
/dev/disk/by-id/scsi-
/dev/sda
36003005700026cc011251e4b0b80ac59
/dev/disk/by-id/scsi-
/dev/sdb
3600000e00d0000000001000000000000
/dev/disk/by-id/scsi-
/dev/sdc
