How to enable disk locator on ZFS disk

 How to enable disk locator on ZFS disk:

Suppose there is disk failure on ZFS, we can make disk locator "ON" so the failed disk can be identified easily at the time of disk replacement.

Login to ZFS shell login prompt and run below commands:

==================================================

ZFSC1:> maintenance hardware

ZFSC1:maintenance hardware> list

             NAME         STATE     MANUFACTURER  MODEL                     SERIAL        RPM    TYPE

chassis-003  1645HEN05Y   faulted   Oracle        Oracle Storage DE2-24C    1645HEN05Y    7200   hdd

Here for chasis (chassis-000, chassis-001, chassis-002 etc..) the disk status is showing as 'OK' and for chassis-003 it is showing status as 'faulted' so we can say one of the disk present in chasis-003 could be failed.

Rules For Setting Name Number in Numerology

Rules For Name Number in Numerology:

Driver means Mulank

Conductor means Bhagyank 

In modern numerology we consider 1,5 and 6 are luckiest numbers so we try to set name number on theses numbers only. But before doing that we have follow certain rules. I have given below the rules for setting name number:

Rule 1 : If 5 number is missing in your Loshu Grid (Numero-scope) then always and always bring your name number on 5 (like 5,14,23,32,41,50 etc..) Blindly we can follow this rule. 

            Reason : Because 5 is not having any anti or enemy number. 5 comes to center of grid and we call it as "Bramh-sthan" which gives balance or stability.

Rule 2 : If someone is not knowing his/her birthdate or there is some confusion in his/her birthdate then without any hesitation go for Name Number 5.

Rule 3 : If you have 1,5,6 number in your Loshu grid and your Driver or Conductor is not anti of 1 (like 8 is anti of 1) then taking Name Number to 1 is best choice. 

             Reason : More 1 is always best, because 1 number signify sun or king and all planets take energy from Sun. Repeating 1 numbers can give you fame and success. 

Rule 4 : If your Driver and/or Conductor is anti of 1 then you have to bring your Name Number for 5 and/or 6 . 

             Example : Suppose my Driver or conductor is 8 then taking name number on 1 will be a bad choice because 8 and 1 are enemy numbers of each other.

Rule 5 : If your Driver and/or Conductor is 3 or 9 then you have to bring your Name Number either on 5  or 1 and not on 6 number. 

             Example : Suppose my Driver or conductor is 3 then taking name number on 6 will be bad choice because 3 and 6 are enemy numbers of each other.

Rule 6 : If 5 and 6 is already in grid then avoid to Name number to 5 or 6 . (Will discuss on this in repeating numbers)

Rule 7 : Always check your Driver and Conductor common friend numbers. Avoid anti numbers of your Driver and Conductor ( 1 is anti with 8 or 3 is anti with 6 or vice versa) for setting your name.

Rule 8 : 99% avoid decreasing name spelling. 1 % scope is there, so if no other choice then Name number spelling can be decreased. Don't be rigid.

Rule 9 : Always try to correct your name. If not possible then touch surname.

Rule 10 : If you first name number is coming on 2,4,8 (which we consider struggling numbers) and full name number is on 1,5,6 then always write full name and never write only first name.                              Whenever you want to use your first name only better to bring it on 1,5,6 to use it.
