bosboot: Boot image is 22995 512 byte blocks.

My mksysb scripts gives the following text on standard error:
bosboot: Boot image is 22995 512 byte blocks.

How come on a Aix 5200-07 aix-system.

I thought this message meant that the tape (/dev/rmt0) is not bootable,
but I read about a limit of 12 MB and 22995 block is less than 12 MB

Or is something else the problem?
By the way, this errors goes on 3 of our machines:

7026-H50
P660

NAME
hp - RH-11/RP04, RP05, RP06 moving-head disk DESCRIPTION
The octal representation of the minor device number is encoded idp, where i is an interleave flag, d is a physical drive number, and p is a pseudodrive (subsection) within a physical unit. If i is 0, the origins and sizes of the pseudodisks on each drive, counted in cylinders of 418 512-byte blocks, are: disk start length 0 0 23 1 23 21 2 0 0 3 0 0 4 44 386 5 430 385 6 44 367 7 44 771 If i is 1, the minor device consists of the specified pseudodisk on drives numbered 0 through the designated drive number. Successively numbered blocks are distributed across the drives in rotation. Systems distributed for these devices use disk 0 for the root, disk 1 for swapping, and disk 4 (RP04/5) or disk 7 (RP06) for a mounted user file system. The block files access the disk via the system's normal buffering mechanism and may be read and written without regard to physical disk records. A `raw' interface provides for direct transmission between the disk and the user's read or write buffer. A single read or write call results in exactly one I/O operation and therefore raw I/O is considerably more efficient when many words are transmitted. The names of the raw files conventionally begin with an extra `r.' In raw I/O the buffer must begin on a word boundary, and raw I/O to an interleaved device is likely to have disappointing results. FILES
/dev/rp?, /dev/rrp? SEE ALSO
rp(4) BUGS
In raw I/O read and write(2) truncate file offsets to 512-byte block boundaries, and write scribbles on the tail of incomplete blocks. Thus, in programs that are likely to access raw devices, read, write and lseek(2) should always deal in 512-byte multiples. Raw device drivers don't work on interleaved devices. HP(4)
