When a LV is mirrored you have at least twice the number of PP than LPs. In the example above you can see, that all LVs are mirrored but the 2 sysdump devices lg_dumplv and lg_dumplv2.
Increasing a filesystem by blocks, megabytes or something will at least always allocate up to the full size of the next PP. So if you are at the "border" to the next PP and tell the system you need 200 MB more space in the FS, and have 100 MB left in the current PP, it will use it up and get the next full PP too. Let's say you have a size of 256 MB per PP, it would allocate 100 MB of the current PP and all 256 MB of the next PP. Your FS would be larger by 356 MB instead of only 200 MB. You will see more LPs & PPs allocated and if it is a mirrored LV, you will see even more PPs
But this is nothing to worry about - this is normal.

So, we removed a LUN from the SAN and the system is refusing to remove the references to it in the /dev folder. I've done the following:
devfsadm -Cv
powermt -q
luxadm -e offline <drive path>
luxadm probe
All those commands failed to remove the path. The drive stills shows up as <drive... (13 Replies)
Hi,
How can i check that i am using RAW devices for storage in my AIX machine...
Also after adding a LUN from storage to a aix host, when i check /dev in the host, i can see both rhdisk and hdisk with same number

Hello AIXians,
I can't boot my AIX, it hangs and stops at the code error: 0518
After searching google, I knew the problem is due to problems in File Systems.
So the solution is booting from any bootable media, then run these commands in maintenance mode:
#fsck -y /dev/hd4

newfs_exfat
NEWFS_EXFAT(8) BSD System Manager's Manual NEWFS_EXFAT(8)NAME
newfs_exfat -- construct a new ExFAT file system
SYNOPSIS
newfs_exfat [-N] [-R] [-I volume-serial-number] [-S bytes-per-sector] [-a sectors-per-FAT] [-b bytes-per-cluster] [-c sectors-per-cluster]
[-n number-of-FATs] [-s total-sectors] [-v volume-name] special
DESCRIPTION
The newfs_exfat utility creates an ExFAT file system on device special. If the -R option is not given, and the device is already formatted
as ExFAT, it will preserve the partition offset, bytes per cluster, FAT offset and size, number of FATs, offset to start of clusters, number
of clusters, volume serial number, and volume name (label). If a volume name was specified via the -v option, that name is used instead of
the volume's previous name.
The options are as follow:
-N Don't create a file system: just print out parameters.
-R Do not check whether the device is currently formatted as ExFAT. Always derive the partition offset, bytes per cluster, FAT offset
and size, and offset to start of clusters based on the device type and size.
-I volume-serial-number
Volume ID, a 32-bit integer.
-S bytes-per-sector
Number of bytes per sector. Acceptable values are powers of 2 in the range 512 through 4096.
-a sectors-per-FAT
Number of sectors per FAT.
-b bytes-per-cluster
File system block size (bytes per cluster). Acceptable values are powers of 2 in the range 512 through 33554432.
-c sectors-per-cluster
Sectors per cluster. Acceptable values are powers of 2 in the range 1 through 65536.
-n number-of-FATs
Number of FATs. Acceptable values are 1 or 2. The default is 1. Using any value other than 1 is discouraged, and may be incompati-
ble with other devices.
-s total-sectors
The total number of sectors in the device.
-v volume-name
Volume name (label). The name will be converted to UTF-16, and must be no longer than 11 UTF-16 characters. ASCII control charac-
ters and some punctuation characters are not allowed (similar to DOS 8.3-style names). NOTE: The volume name may be an empty (zero-
length) string.
EXAMPLES
newfs_exfat /dev/disk0s1
Create a file system, using default parameters (or existing ExFAT layout), on /dev/rdisk0s1.
newfs_exfat -v Hello disk2s1
Create a file system with the name "Hello" on /dev/rdisk2s1.
SEE ALSO mount_exfat(8), fsck_exfat(8)DIAGNOSTICS
Exit status is 0 on success and 1 on error.
HISTORY
The newfs_exfat command appeared in Mac OS X 10.6.3.
