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)
Hello All,

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
1)Physical Volume
2)Volume Group
3)Logical Volume
4)Physical Partition
Please help me to understand these concepts. (6 Replies)

hdio(7I) Ioctl Requests hdio(7I)NAME
hdio - SMD and IPI disk control operations
SYNOPSIS
#include <sys/hdio.h>
DESCRIPTION
Note - The SMC and IPI drivers have been discontinued. dkio(7I) is now the preferred method for retrieving disk information.
The SMD and IPI disk drivers supplied with this release support a set of ioctl(2) requests for diagnostics and bad sector information.
Basic to these ioctl() requests are the definitions in <sys/hdio.h>.
IOCTLS
HDKIOCGTYPE The argument is a pointer to a hdk_type structure (described below). This ioctl() gets specific information from the hard
disk.
HDKIOCSTYPE The argument is a pointer to a hdk_type structure (described below). This ioctl() sets specific information about the hard
disk.
/*
* Used for drive info
*/
struct hdk_type {
ushort_t hdkt_hsect; /* hard sector count (read only) */
ushort_t hdkt_promrev; /* prom revision (read only) */
uchar_t hdkt_drtype; /* drive type (ctlr specific) */
uchar_t hdkt_drstat; /* drive status (ctlr specific, ro) */
};
HDKIOCGBAD The argument is a pointer to a hdk_badmap structure (described below). This ioctl() is used to get the bad sector map from
the disk.
HDKIOCSBAD The argument is a pointer to a hdk_badmap structure (described below). This ioctl() is used to set the bad sector map on
the disk.
/*
* Used for bad sector map
*/
struct hdk_badmap {
caddr_t hdkb_bufaddr; /* address of user's map buffer */
};
HDKIOCGDIAG The argument is a pointer to a hdk_diag structure (described below). This ioctl() gets the most recent command that failed
along with the sector and error number from the hard disk.
/*
* Used for disk diagnostics
*/
struct hdk_diag {
ushort_t hdkd_errcmd; /* most recent command in error */
daddr_t hdkd_errsect; /* most recent sector in error */
uchar_t hdkd_errno; /* most recent error number */
uchar_t hdkd_severe; /* severity of most recent error */
};
