Rebooting the Linux Server
Reboot the Linux server.
Execution example
# shutdown -r now
8.5
Recognizing LUNs
After rebooting, 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. For
example, if there is one internal SCSI disk and three ETERNUS Disk storage system LUNs,
SCSI device names are assigned as follows:
SCSI device name
dev/sda
/dev/sdb
/dev/sdc
/dev/sdd

ETERNUS Disk storage systems Server Connection Guide (iSCSI) for Linux
(SUSE Linux Enterprise Server)
Enter the Password that is set in "Set iSCSI Port Parameters" of the ETERNUS Disk
storage system in "Password".
Click the [Next] button.
After both path logins have completed, check that the information of the desired
Target is visible in the "Connected Targets" of the iSCSI Initiator Overview.
Make sure that "Start-Up" for the desired Target is set to "automatic" (if currently
set to "manual", select the Target and click the [Toggle Start_Up] button), then
click the [Finish] button.
