Manual for XPINFO ?

NAME
xpinfo - Enhanced SCSI Inquiry for SureStore E XP Disk Array

SYNOPSIS
xpinfo -[tu] [-v] -[l|p] -[i|c|h|m|r|d[char]] [-f raw_device]

DESCRIPTION
xpinfo provides a mapping between the device file(s) on HP-UX and the
associated port and ldev on the SureStore E XP Disk Array. By
default, this utility will provide a name cross reference of all luns
connected to the array.


Options
-c Displays Continuous Access and Business Copy volume
designation information. Data fields include: subsystem
number, CT group number, CA volume designation, and BC
volume designation for each of the three MU numbers.

-d[char]
Displays a single line of data per logical device.
Each data field is delimited by a comma or by 'char' if
specified. The ordering of the data fields is as follows:
device_file, target_id, LUN_id, port_id, CU:LDev, type,
device_size, serial#, code_rev, subsystem, CT_group, CA_vol,
BC0_vol, BC1_vol, BC2_vol, ACP_pair, RAID_level, RAID_group,
disk1, disk2, disk3, disk4, model, port_WWN, ALPA.
Fields for which the data is either not available or not
applicable for the device are displayed as "---".

-f raw_device
Report information only for the specified logical device.
By default (-f not specified), this tool will report on
all "OPEN" type devices.

-h Displays this help message.

-i Displays identification information. Data fields
include: ALPA, target id, LUN id, port id, LDev number,
LUN type (product id) and serial number.

-l Sort output by LDev number.

-m Displays model information. Data fields include:
model id, emulation type, size, serial number and
firmware revision.

-p Sort output by Port number.

-r Displays RAID configuration information. Data fields
include: ACP pair number, RAID level, RAID group, and
disk mechanisms.

-t Display Target, Lun, CU and LDev id's in decimal format.
The default is to display in hexadecimal format.

-u Create report using updated ioscan list. By default, the
report is created using the kernel image of the last ioscan.

-v Display xpinfo version. The -v option has precedence over
all other options. If the -v option is specified along with
other output options, only the xpinfo revision is displayed.


By default, (options i,c,m,r,d not specified) xpinfo will display in
verbose format.


EXAMPLES
The following command will provide a mapping of the disk device file
c20t7d2

xpinfo -f /dev/rdsk/c116t2d1

which results in the following output:

Device File : /dev/rdsk/c116t2d1 Model : XP512
Port : CL2C Serial # : 00030057
Host Target : 02 Code Rev : 0116
Array LUN : 11 Subsystem : 0004
CU:LDev : 00:11 CT Group : ---
Type : OPEN-3 CA Volume : SMPL
Size : 2347 MB BC0 (MU#0) : SMPL
ALPA : da BC1 (MU#1) : SMPL
Loop Id : 07 BC2 (MU#2) : SMPL
SCSI Id : --- RAID Level : RAID5
FC-LUN : 4011000000000000 RAID Group : 1-2
Port WWN : 500060e802756912 ACP Pair : 1
Disk Mechs : R101 R111 R121 R131

This is the verbose format output, which includes all data gathered
for the device.

Note:

1. If the LUN is not paired for Async, then the CT Group number
is displayed as "---".

2. For Fibre Channel attach LUNs the Target field provides the
FC-AL Loop ID and the LUN field provides the FCP_LUN ID.

3. Fields for which the data is either not available or not

applicable for the device are displayed as "---". Read More..

please ignore the error above, the shc already linked to /usr/local/bin

3.Create shell script file to do test

[root@Redhat6_afgan shc-3.8.7] # vi afgan.sh

#!/bin/bash

echo "please Call Me AFGAN !!!"

:wq!

[root@Redhat6_afgan shc-3.8.7]#

[root@Redhat6_afgan shc-3.8.7]# chmod +x afgan.sh

[root@Redhat6_afgan shc-3.8.7] # ls -ltr afgan.sh

-rwxr-xr-x. 1 root root   45 Jan 19 17:05 afgan.sh

[root@Redhat6_afgan shc-3.8.7]#

4.Try complie the script using shc

[root@Redhat6_afgan shc-3.8.7]# /usr/local/bin/shc  -v -r -T -f afgan.sh

shc shll=bash

shc [-i]=-c

shc [-x]=exec '%s' "$@"

shc [-l]=

shc opts=

shc: cc  afgan.sh.x.c -o afgan.sh.x

shc: strip afgan.sh.x

shc: chmod go-r afgan.sh.x

[root@Redhat6_afgan shc-3.8.7]#

[root@Redhat6_afgan shc-3.8.7]# ls -ltr afgan*

-rw-r--r--. 1 root root   45 Jan 19 17:05 afgan.sh

-rw-r--r--. 1 root root 9450 Jan 19 17:08 afgan.sh.x.c

-rwx--x--x. 1 root root 9240 Jan 19 17:08 afgan.sh.x

[root@Redhat6_afgan shc-3.8.7]#

After compile shell script file, shc will create 2 files : afgan.sh.x and afgan.sh.x.c 

[root@Redhat6_afgan shc-3.8.7]# file afgan.sh

[root@Redhat6_afgan shc-3.8.7]# file afgan.sh.x.c

afgan.sh.x.c: ASCII C program text

[root@Redhat6_afgan shc-3.8.7]# file afgan.sh.x

afgan.sh.x: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped

[root@Redhat6_afgan shc-3.8.7]#

5. Test running the ooutput file from shc

[root@Redhat6_afgan shc-3.8.7]# pwd

/root/test/shc-3.8.7/shc-3.8.7

[root@Redhat6_afgan shc-3.8.7]# ls -ltr afgan*

-rwxr-xr-x. 1 root root   45 Jan 19 17:05 afgan.sh

-rw-r--r--. 1 root root 9450 Jan 19 17:08 afgan.sh.x.c

-rwx--x--x. 1 root root 9240 Jan 19 17:08 afgan.sh.x

[root@Redhat6_afgan shc-3.8.7]# ./afgan.sh.x

please Call Me AFGAN !!!

[root@Redhat6_afgan shc-3.8.7]#

6. Rename file afgan.sh.x with whatever your needed

How to reduce FileSystem LVM in Redhat 6

Here are steps to reduce filesystem in Linux Redhat 6 (please do full backup before your execute reducing filesystem) :

1. Umount Filesystem
[root@RedHat6]# umount /oravl99

2. Fsck that filesystem.
[root@RedHat6]# e2fsck -f /dev/vg_arch/oravl99
e2fsck 1.41.12 (17-May-2010)
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
/dev/vg_arch/oravl99: 11/131072 files (0.0% non-contiguous), 16821/510976 blocks

3. Resize filesystem. example wanto to reduce 1G for existing filesystem
[root@RedHat6]# resize2fs -p /dev/vg_arch/oravl99 1G
resize2fs 1.41.12 (17-May-2010)
Resizing the filesystem on /dev/vg_arch/oravl99 to 262144 (4k) blocks.
Begin pass 3 (max = 16)
Scanning inode table          XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
The filesystem on /dev/vg_arch/oravl99 is now 262144 blocks long.

4. reduce 1Gb on the filesystem
[root@RedHat6]# lvreduce -L 1Gb /dev/vg_arch/oravl99
  WARNING: Reducing active logical volume to 1.00 GiB
  THIS MAY DESTROY YOUR DATA (filesystem etc.)
Do you really want to reduce oravl99? [y/n]: y
  Reducing logical volume oravl99 to 1.00 GiB
  Logical volume oravl99 successfully resized

5. Mount Filesystem
[root@RedHat6]# mount /oravl99

6. Check sizing current filesystem
[root@RedHat6]# df -h /oravl99
/dev/mapper/vg_arch-oravl99
                     1008M   34M  924M   4% /oravl99

How to Extend LVM linux RedHat 6

Here are steps to extend and reduse LVM in Linux Redhat 6

1. Check sizing Volume group that filesystem want to changes

[root@RedHat6]# uname -sr Linux 2.6.32-71.el6.x86_64
[root@RedHat6]# vgs
VG #PV #LV #SN Attr VSize VFree
vg00 1 1 0 wz--n- 1020.00m 0
vgVo 1 1 0 wz--n- 3.41g 0
 vg_arch 1 1 0 wz--n- 1.95g 972.00m 
vgswap 1 1 0 wz--n- 508.00m 0
[root@RedHat6]#


[root@RedHat6]# vgdisplay vg_arch
  --- Volume group ---
  VG Name               vg_arch
  System ID
  Format                lvm2
  Metadata Areas        1
  Metadata Sequence No  2
  VG Access             read/write
  VG Status             resizable
  MAX LV                0
  Cur LV                1
  Open LV               1
  Max PV                0
  Cur PV                1
  Act PV                1
  VG Size               1.95 GiB
  PE Size               4.00 MiB
  Total PE              499
  Alloc PE / Size       256 / 1.00 GiB
  Free  PE / Size       243 / 972.00 MiB
  VG UUID               qjyTfj-UMKx-uFDo-L1BE-xf4t-cD9O-myqJC3
[root@RedHat6]#

2. Ok, we have 972Mb free size on vg_arch and then we can add that to filesystem oravl99

[root@RedHat6]# lvs
  LV      VG      Attr   LSize    Origin Snap%  Move Log Copy%  Convert
  prod    vg00    -wi-ao 1020.00m
  lvVo    vgVo    -wi-ao    3.41g
  oravl99 vg_arch -wi-ao    1.00g
  LSWAP   vgswap  -wi-ao  508.00m
[root@RedHat6


[root@RedHat6]# lvextend -l +243 /dev/vg_arch/oravl9
Extending logical volume oravl99 to 1.95 GiB
Logical volume oravl99 successfully resized
[root@RedHat6]

===== OR we can use below command =========
[root@RedHat6]# lvextend -L +972M /dev/vg_arch/oravl99
  Extending logical volume oravl99 to 1.95 GiB
  Logical volume oravl99 successfully resized
[root@RedHat6]#
====================================

[root@RedHat6]# lvs
LV      VG      Attr   LSize    Origin Snap%  Move Log Copy%  Convert
prod    vg00    -wi-ao 1020.00m
lvVo    vgVo    -wi-ao    3.41g
oravl99 vg_arch -wi-ao    1.95g
LSWAP   vgswap  -wi-ao  508.00m
[root@RedHat6]

3. resizing filesystem oravl99

[root@RedHat6]# resize2fs /dev/vg_arch/oravl99
resize2fs 1.41.12 (17-May-2010)
Filesystem at /dev/vg_arch/oravl99 is mounted on /oravl99; on-line resizing required
old desc_blocks = 1, new_desc_blocks = 1
Performing an on-line resize of /dev/vg_arch/oravl99 to 510976 (4k) blocks.
The filesystem on /dev/vg_arch/oravl99 is now 510976 blocks long.

[root@RedHat6]# df -h /oravl99
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg_arch-oravl99
                      2.0G   34M  1.8G   2% /oravl99
[root@RedHat6]#
