Locked

Dear Erman,
I am expecting to get the WWID of all the disks as below Disk: sda WWID: 3600601602b702d006218b7de8130e111 Disk: sdaa WWID: 3600601602b702d000652b695c648e111 Disk: sdab WWID: 3600601602b702d000752b695c648e111 Disk: sdac WWID: 3600601602b702d007f2a73fbc648e111 Disk: sdad WWID: 3600601602b702d007e2a73fbc648e111 I have got the script something like: #!/bin/ksh for disk in `ls /dev/sd*` do disk_short=`basename $disk` wwid=`/usr/lib/udev/scsi_id -g -u -s /block/$disk_short` if [ "$wwid" != "" ] then echo -e "Disk:" $disk_short "\tWWID:" $wwid fi done But when i ran it,we are facing invalid option error as below [root@erpuatdb1 etc]# sh abc.sh /usr/lib/udev/scsi_id: invalid option -- 's' /usr/lib/udev/scsi_id: invalid option -- 's' /usr/lib/udev/scsi_id: invalid option -- 's' /usr/lib/udev/scsi_id: invalid option -- 's' /usr/lib/udev/scsi_id: invalid option -- 's' /usr/lib/udev/scsi_id: invalid option -- 's' /usr/lib/udev/scsi_id: invalid option -- 's' /usr/lib/udev/scsi_id: invalid option -- 's' /usr/lib/udev/scsi_id: invalid option -- 's' /usr/lib/udev/scsi_id: invalid option -- 's' /usr/lib/udev/scsi_id: invalid option -- 's' we are using Red Hat Enterprise Linux Server release 7.3 (Maipo) Thank you |

it seems "-s" is not a valid argument for the scsi_id program that is delivered with Redhat 7.
you can check it using "man scsi_id" command. Why do you use "-s" argument anyways? |

Thanks erman for the update.
I got this script from internet.Tried removing -s but not getting any output [root@erpproddb1 ~]# sh scsc_id.sh [root@erpproddb1 ~]# [root@erpproddb1 ~]# /usr/lib/udev/scsi_id --help Usage: scsi_id [OPTION...] DEVICE SCSI device identification. -h --help Print this message --version Print version of the program -d --device= Device node for SG_IO commands -f --config= Location of config file -p --page=0x80|0x83|pre-spc3-83 SCSI page (0x80, 0x83, pre-spc3-83) -s --sg-version=3|4 Use SGv3 or SGv4 -b --blacklisted Treat device as blacklisted -g --whitelisted Treat device as whitelisted -u --replace-whitespace Replace all whitespace by underscores -v --verbose Verbose logging -x --export Print values as environment keys [root@erpproddb1 ~]# |

First check the command , then the script.
First check the command starting with scsi_id. Ensure it is working, and then go into the script. Check scsi_id command! For example: scsi_id -g -u -d /dev/sdb scsi_id -g -u -d /dev/sdb1 Are these commands working? |

You are right erman.We are able to get the output of scsi_id -g -u -d /dev/sdb.Then we have identified the issue with the script
Original script [root@erpproddb1 ~]# cat a.sh #!/bin/ksh -x for disk in `ls /dev/sd*` do disk_short=`basename $disk` wwid=`/usr/lib/udev/scsi_id -g -u -d /block/$disk_short` if [ "$wwid" != "" ] then echo -e "Disk:" $disk_short "\tWWID:" $wwid fi done Modified script [root@node1~]# cat a.sh #!/bin/ksh -x for disk in `ls /dev/sd*` do disk_short=`basename $disk` wwid=`/usr/lib/udev/scsi_id -g -u -d /dev/$disk_short` if [ "$wwid" != "" ] then echo -e "Disk:" $disk_short "\tWWID:" $wwid fi done and now,with modifed script,we got what we are expecting as below [root@erpproddb1 ~]# sh a.sh Disk: sda WWID: 3600508b1001caec3c0f4e9d6f7cba720 Disk: sda1 WWID: 3600508b1001caec3c0f4e9d6f7cba720 Disk: sda2 WWID: 3600508b1001caec3c0f4e9d6f7cba720 Disk: sda3 WWID: 3600508b1001caec3c0f4e9d6f7cba720 Disk: sdaa WWID: 360002ac0000000000000008b0001c9fc Disk: sdab WWID: 360002ac000000000000000850001c9fc Disk: sdac WWID: 360002ac000000000000000800001c9fc Disk: sdad WWID: 360002ac000000000000000810001c9fc Disk: sdae WWID: 360002ac000000000000000820001c9fc Disk: sdaf WWID: 360002ac0000000000000007f0001c9fc Disk: sdag WWID: 360002ac000000000000000830001c9fc Disk: sdah WWID: 360002ac000000000000000870001c9fc Disk: sdai WWID: 360002ac000000000000000880001c9fc Disk: sdaj WWID: 360002ac000000000000000860001c9fc Disk: sdak WWID: 360002ac000000000000000890001c9fc Disk: sdal WWID: 360002ac000000000000000840001c9fc Disk: sdam WWID: 360002ac0000000000000007d0001c9fc Disk: sdan WWID: 360002ac0000000000000007b0001c9fc Disk: sdao WWID: 360002ac0000000000000007a0001c9fc Disk: sdap WWID: 360002ac0000000000000007c0001c9fc Disk: sdaq WWID: 360002ac000000000000000790001c9fc Disk: sdar WWID: 360002ac0000000000000007e0001c9fc Disk: sdas WWID: 360002ac000000000000000780001c9fc Disk: sdat WWID: 360002ac000000000000000b20001c9fc Disk: sdau WWID: 360002ac000000000000000b30001c9fc Disk: sdav WWID: 360002ac000000000000000b40001c9fc Disk: sdaw WWID: 360002ac000000000000000b50001c9fc Disk: sdax WWID: 360002ac000000000000000b60001c9fc Disk: sday WWID: 360002ac000000000000000b70001c9fc Disk: sdaz WWID: 360002ac000000000000000b80001c9fc Disk: sdb WWID: 360002ac000000000000000070001c9fc Disk: sdba WWID: 360002ac000000000000000b90001c9fc Disk: sdbb WWID: 360002ac000000000000000ba0001c9fc Disk: sdbc WWID: 360002ac000000000000000bb0001c9fc Disk: sdbd WWID: 360002ac000000000000000bd0001c9fc Disk: sdbe WWID: 360002ac000000000000000bc0001c9fc Disk: sdbf WWID: 360002ac000000000000000be0001c9fc Disk: sdbg WWID: 360002ac000000000000000bf0001c9fc Disk: sdbh WWID: 360002ac000000000000000c00001c9fc Disk: sdbi WWID: 360002ac000000000000000070001c9fc Disk: sdbj WWID: 360002ac000000000000000080001c9fc Disk: sdbk WWID: 360002ac000000000000000b10001c9fc Disk: sdbl WWID: 360002ac000000000000000540001c9fc Disk: sdbm WWID: 360002ac000000000000000630001c9fc Disk: sdbn WWID: 360002ac000000000000000640001c9fc Disk: sdbo WWID: 360002ac000000000000000650001c9fc Disk: sdbp WWID: 360002ac000000000000000580001c9fc Disk: sdbq WWID: 360002ac000000000000000660001c9fc Disk: sdbr WWID: 360002ac000000000000000670001c9fc Disk: sdbs WWID: 360002ac000000000000000680001c9fc Disk: sdbt WWID: 360002ac000000000000000690001c9fc Disk: sdbu WWID: 360002ac0000000000000006a0001c9fc Disk: sdbv WWID: 360002ac0000000000000006b0001c9fc Disk: sdbw WWID: 360002ac0000000000000006c0001c9fc Disk: sdbx WWID: 360002ac0000000000000006d0001c9fc Disk: sdby WWID: 360002ac0000000000000006e0001c9fc Disk: sdbz WWID: 360002ac0000000000000006f0001c9fc Disk: sdc WWID: 360002ac000000000000000080001c9fc Disk: sdca WWID: 360002ac000000000000000750001c9fc Disk: sdcb WWID: 360002ac000000000000000760001c9fc Disk: sdcc WWID: 360002ac000000000000000770001c9fc Disk: sdcd WWID: 360002ac0000000000000008a0001c9fc Disk: sdce WWID: 360002ac0000000000000008c0001c9fc Disk: sdcf WWID: 360002ac0000000000000008d0001c9fc Disk: sdcg WWID: 360002ac000000000000000890001c9fc Disk: sdch WWID: 360002ac0000000000000008b0001c9fc Disk: sdci WWID: 360002ac000000000000000850001c9fc Disk: sdcj WWID: 360002ac000000000000000800001c9fc Disk: sdck WWID: 360002ac000000000000000810001c9fc Thanks for all your time.
