Jos�, I'm going to point you to a manual you should read (for future reference), and then tell you how to add your volumes.
Linux/390 2.4 and higher supports dynamic DASD addition/removal. The manual that talks about this is "Linux for S/390 Device Drivers and Installation Commands (Linux Kernel 2.4)" and it can be downloaded from http://www10.software.ibm.com/developerworks/opensource/linux390/docu/l390dd 08.pdf To add a volume (or multiple volumes) issue this command: echo "add device range=123-126 " > /proc/dasd/devices If you then cat /proc/dasd/devices you should see device numbers 123 through 126. If you just want to add one volume, then echo "add device range=123 " > /proc/dasd/devices Use this command twice if the two device numbers are not consecutive. Note the trailing blank on the echo command. There used to be a bug in the interface that made that blank required. The bug may have been fixed, but I'm not sure. After you add the DASD, you'll need to format it: dasdfmt -f /dev/dasdb -b 4096 dasdfmt -f /dev/dasdc -b 4096 The /dev/dasd names will depend on which volumes you just added, so do a cat /proc/dasd/devices to see what they are. After you format the DASD, you'll need to create at least one partition on each of them: fdasd /dev/dasdb fdasd /dev/dasdc You'll be prompted to add a partition, and how big it should be, etc. Again, check to make sure what /dev/dasd names you should be using on your system. After you've created the partitions, you need to make a file system on them: mke2fs -b 4096 /dev/dasdb1 mke2fs -b 4096 /dev/dasdc1 If you created more than one partition, then mke2fs -b 4096 /dev/dasdb1 mke2fs -b 4096 /dev/dasdb2 mke2fs -b 4096 /dev/dasdc1 mke2fs -b 4096 /dev/dasdc2 etc. You should now be ready to mount the file systems and use them. Depending on what file system drivers your system has loaded, you may be able to use ext3, JFS, XFS, Reiserfs, or other file system types. If you're not sure, use ext2 as I did in the samples. To understand these commands more: man dasdfmt man fdasd man mke2fs man mkfs Mark Post -----Original Message----- From: Rugel Jos� [mailto:[EMAIL PROTECTED]] Sent: Friday, January 03, 2003 11:44 AM To: [EMAIL PROTECTED] Subject: Add new 3390 DEV to Linux Hi, I need to adda new two 3390 DEV to Linux.
