size = minsize | remaining
size = minsize | remaining | maxsize
Specifies the size of the volume/file system to be number. In the case the size is set to remain-
ing, the volume is assigned the disk space that is left after allocating all other volumes. If max-
size is specified in conjunction with remaining, the remaining disk space, up to maxsize,is
assigned to the volume. If minsize is specified, the size of the volume is at least that size if there is
sufficient space, and is larger, up to the maxsize value, if possible. number, minsize, and maxsize
may be in units of bytes, or may be in MB or KB (for example: 100MB, 102400KB).
Ignite-UX uses the disk-space impact information supplied with the software selections in deter-
mining the final size requirements for volumes. Ignite-UX does not let a volume size be lower
than the space required to load the selected software. If a volume size is specified smaller than the
software requires, the size will automatically be increased. Ignite-UX attempts to ensure that
some amount of free space is left on each volume after the installation is complete.
The algorithm used when calculating the software impact to volumes is as follows:
• The minimum size that a volume is allowed to be is the software impact, plus 12% (or the file
system minfree percentage if set).
• In addition to this minimum size, a percentage is added to the volumes to ensure sufficient
"breathing room" after the system is installed. This percentage is by default 10%, but may be con-
trolled by the configuration file variable _hp_addnl_fs_free_pct. If the disk capacity is
insufficient to accommodate this additional free space, this additional percentage value is continu-
ally reduced by 1/2 until a value is found that allows all the volumes to fit. If the volumes do not
fit with 0% additional space, the install is not allowed to proceed.
size = percent %free
size = amount free
size = minsize | remaining | percent %free
size = minsize | remaining | amount free
Specifies the size of the volume/file system to be relative to the expected amount of data for that
file system. The size may be specified as a the desired percentage of free space, or the number of
megabytes desired to be free after the installation.
When the size is specified as a range, the size of the volume is allowed to be adjusted down to the
minsize value in order to fit any other volumes into the amount of disk space available. Some
examples follow:
size = 100MB
size = 150MB | remaining | 20% free
size = 30MB free
size = remaining
mount_point = cplx_string
Specifies the directory the file system is mounted under as cplx_string. Specifying a
mount_point for a swap volume is not necessary, but may be performed so that the swap vol-
ume may be uniquely identified if it is to be overridden later in the configuration file.
minfree = number
Sets the percentage of the disk to reserve for root-only use to number.
file_length = SHORT
file_length = LONG
Sets the file system filename length; the default is LONG. This keyword applies to HFS file sys-
tems only; VxFS file systems are always capable of long filenames.
blksize = number
Sets the file system block size to number. This keyword applies to both HFS and VxFS file sys-
tems. Acceptable values of number for HFS file systems are 4096, 8192, 16384, 32768, and
65536; the default is 8192. Acceptable values of number for VxFS file systems are 1024, 2048,
