ダンプデバイスの準備 †
アドレス8107の3390-3型のDASDをダンプ出力先とする。
- 出力先のDASDをLinuxに認識させる

- ダンプ出力先のDASDをフォーマットしパーティションを作成する
# dasdfmt -f /dev/dasdd -b 4096 Drive Geometry: 3339 Cylinders * 15 Heads = 50085 Tracks I am going to format the device /dev/dasdd in the following way: Device number of device : 0x8107 Labelling device : yes Disk label : VOL1 Disk identifier : 0X8107 Extent start (trk no) : 0 Extent end (trk no) : 50084 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
# fdasd -a /dev/dasdd reading volume label ..: VOL1 reading vtoc ..........: ok auto-creating one partition for the whole disk... writing volume label... writing VTOC... rereading partition table...
- ダンプデバイスへのスタンドアローン・ダンププログラム導入
# zipl -d /dev/dasdd1 Dump target: partition '/dev/dasdd1' with a size of 2347 MB. Warning: All information on partition '/dev/dasdd1' will be lost! Do you want to continue creating a dump partition (y/n)?y Done.
