Hi, We were adding a large number of disks to our SuSE8 image. Normally, it adds the dasd as "dasda", "dasdb", etc. When we added disk 27, it adds the dasd as "dasdaa".
Here is the log when the devices were added: dasd(eckd): /dev/dasdaa ( 94:104),[EMAIL PROTECTED]: 3390/0A(CU:3990/01) Cyl:3338 Head:15 dasd(eckd): /dev/dasdaa ( 94:104),[EMAIL PROTECTED]: 3390/0A(CU:3990/01) Cyl:3338 Head:15 dasd(eckd): /dev/dasdaa ( 94:104),[EMAIL PROTECTED]: DIAG210 returned VRDCRCCL = 04, VRDC dasd(eckd): /dev/dasdaa ( 94:104),[EMAIL PROTECTED]: XRC_supported reset because of missi dasd(eckd): /dev/dasdaa ( 94:104),[EMAIL PROTECTED]: 3390/0A(CU:3990/01): Configuration d Apr 22 13:00:02 linvm01 kernel: debug: dasdz: new level 3 Apr 22 13:00:02 linvm01 kernel: dasd(eckd): /dev/dasdaa ( 94:104),[EMAIL PROTECTED]: 3390 Apr 22 13:00:02 linvm01 kernel: dasd(eckd): /dev/dasdaa ( 94:104),[EMAIL PROTECTED]: DIAG 82 dasd(eckd): /dev/dasdy ( 94: 96),[EMAIL PROTECTED]: (4kB blks): 2403360kB at 48kB/trk li Apr 22 13:00:02 linvm01 kernel: dasd(eckd): /dev/dasdaa ( 94:104),[EMAIL PROTECTED]: XRC_ Apr 22 13:00:02 linvm01 kernel: dasd(eckd): /dev/dasdaa ( 94:104),[EMAIL PROTECTED]: 3390 Apr 22 13:00:02 linvm01 kernel: dasd(eckd): /dev/dasdy ( 94: 96),[EMAIL PROTECTED]: (4kB debug: dasdaa: new level 3 The Linux administration group then formatted and made a file system on the various dasd volumes. He had a problem when he went to format the "dasdaa" volume. It could not find the "dasdaa" device. He created it, and then he could format it. When he tried to make a files system, it again failed. When he creates the filesystem, he specifies the dasd without a number, ie. "dasdj", "dasdk", etc. I noticed in Mark Post's presentation , he has the following: > 2.4.x Kernels > mke2fs -b 4096 /dev/dasd?1,2,3 > mke2fs -b 4096 /dev/dasda1 > mke2fs -b 4096 /dev/dasda2 > mke2fs -b 4096 /dev/dasda3 What is the difference betweem 1, 2, and 3. Also, why did the system not create the "dasdaa", and "dasdaa1" information? Is there something special we must do when we reach disk number 27? Are the numbers used if you partition the drive into smaller areas? We only have one area on the disk, so I would guess that it would be the "1". Here is the log: linvm01:~ # dasdfmt -b 4096 -d ldl -f /dev/dasdaa dasdfmt: Unable to open device /dev/dasdaa: No such file or directory This was true: linvm01:~ # ls -la /dev/dasda* brw-rw---- 1 root disk 94, 0 Nov 6 2002 /dev/dasda brw-rw---- 1 root disk 94, 1 Nov 6 2002 /dev/dasda1 brw-rw---- 1 root disk 94, 2 Nov 6 2002 /dev/dasda2 brw-rw---- 1 root disk 94, 3 Nov 6 2002 /dev/dasda3 And then (checking major/minor numbers before) linvm01:~ # mknod -m 660 /dev/dasdaa b 94 104 linvm01:~ # ls -la /dev/dasdaa brw-rw---- 1 root root 94, 104 Apr 22 17:27 /dev/dasdaa linvm01:~ # chown root:disk /dev/dasdaa linvm01:~ # ls -la /dev/dasdaa brw-rw---- 1 root disk 94, 104 Apr 22 17:27 /dev/dasdaa Afterwards dasdformat runs without complains. linvm01:~ # dasdfmt -b 4096 -d ldl -f /dev/dasdaa Drive Geometry: 3338 Cylinders * 15 Heads = 50070 Tracks I am going to format the device /dev/dasdaa in the following way: Device number of device : 0x274 Labelling device : yes Disk label : LNX1 Disk identifier : 0X0274 Extent start (trk no) : 0 Extent end (trk no) : 50069 Compatible Disk Layout : no Blocksize : 4096 --->> ATTENTION! <<--- All data of that device will be lost.
