The IBM® iSeries™ Integrated Server Support installation process creates two disk drives (network server storage spaces) for installing and running integrated servers. See Disk drives for integrated Windows servers. By default, i5/OS™ creates these disk drives in the system disk pool (ASP), but you can choose a different location during the installation. i5/OS also uses these disk drives to load and start the integrated server.
Servers have these predefined disk drives:
The C drive ranges from 1,024 to 1,024,000 MB. You can choose to leave the drive as FAT. The C drive is automatically converted to NTFS, if required by the size of the storage space.
Attention: This drive must remain as a FAT drive. Do not make any changes to this drive. i5/OS uses this drive to perform code updates, and changing the drive can make performing updates impossible.
