I am trying to replace an old 9gb hard disk for a 36gb hard drive on an AIX 4.3.2 system (can't update)
I was thinking of doing this by doing a dd from the 9gb to the 36gb hard drive and then resize the Logical Volumes. However, lspv <36gb hard disk> gives me the folowing:
I can only allocate an extra 29 PPs = 464mb. Where are the rest of the PPs of how can I increase the PP size?
Or should I be using a different way to upgrade the (boot)disk?
Hi Everyone,
Can someone tell me the effect of the pp size of the volume group created for Oracle data.
It would seem that creating small pp's will cause more overhead. What if you make the pp to large? What should I base this size on?
Thanks, (4 Replies)
hi,
1) is logical partition the same as physical partition except that one is physical and the other is logical?
2) then it must a one to one ratio? (3 Replies)
Hello,
I need explanations about physical disks and physical volumes. What is the difference between these 2 things?
In fact, i am trying to understand what the AIX lspv2command does.
Thank you in advance. (2 Replies)
I was in smit, checking on disc space, etc. and it appears that one of our physical volumes that is part of a large volume group, has no free physical partitions. The server is running AIX 5.1. What would be the advisable step to take in this instance? (9 Replies)

Hi,
I am new to unix. I am working on Red Hat Linux and side by side on AIX also. After reading the concepts of Storage, I am now really confused regarding the terminologies

WREN(3) Library Functions Manual WREN(3)NAME
wren, ata - hard disk interface
SYNOPSIS
bind #H[drive] /dev
bind #w[target[.lun]] /dev
/dev/hd0disk
/dev/hd0partition
/dev/sd0disk
/dev/sd0partition
...
DESCRIPTION
The hard disk interfaces (wren, #w, is a SCSI disk; ata, #H, is an IDE or ATA disk) serve a one-level directory giving access to the hard
disk partitions. The parameter to attach defines the numerical SCSI target and logical unit number or the IDE drive number to access.
Both default to zero.
Each partition name is prefixed by hd and the numeric drive identifier. The partition always exists and covers the entire disk. The size
of each partition as reported by stat(2) is the number of bytes in the partition, so the size of is the size of the entire disk.
The partition also always exists; it is the last block on the disk for SCSI, second to last for IDE. If it contains valid partition data,
those partitions will be visible as well. Every time the device is bound, the partitions are updated to reflect any changes in the parti-
tion file.
The format of the partition file is the string
plan9 partitions
on a line, followed by partition specifications, one per line, consisting of a name and textual strings for the block start and limit for
each partition on the disk.
The program prep(8) writes the partition table for the disk; its use is preferred to writing it by hand.
