Cpfmtxa from zVM, this will get rid of your first track error. And then
1. To see the DASD devices recognized by Linux, issue the following command: # cat /proc/dasd/devices 0201(ECKD) at ( 94: 0) is dasda : active at blocksize: 4096, 36000 blocks, 140 MB 0202(ECKD) at ( 94: 4) is dasdb : active at blocksize: 4096, 564840 blocks, 2206 MB 0203(ECKD) at ( 94: 8) is dasdc : active at blocksize: 4096, 36000 blocks, 140 MB 0204(ECKD) at ( 94: 12) is dasdd : active at blocksize: 4096, 36000 blocks, 140 MB 2. To format a single DASD device, a block size of 4 KB is recommended. Use the following command: # dasdfmt -b 4096 -f /dev/dasdc Drive Geometry: 200 Cylinders * 15 Heads = 3000 Tracks I am going to format the device /dev/dasdc in the following way: Device number of device : 0x203 Labelling device : yes Disk label : VOL1 Disk identifier : 0X0203 Extent start (trk no) : 0 Extent end (trk no) : 2999 Compatible Disk Layout : yes Blocksize : 4096 --->> ATTENTION! <<--- All data of that device will be lost. Type "yes" to continue, no will leave the disk untouched: yes Formatting the device. This may take a while (get yourself a coffee). Finished formatting the device. Rereading the partition table... ok Answer yes to the query. 3. To create a single partition from a formatted DASD, use the -a flag of the fdasd command. If the -a flag is omitted, an interactive formatting session similar to the PC fdisk command is invoked, as follows: # fdasd -a /dev/dasdc auto-creating one partition for the whole disk... writing volume label... writing VTOC... rereading partition table..
