-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.
