1: change the LV status: from closed/sysncd to: /open/sysncd:

2:make one copy of the lv:

                                Add Copies to a Logical Volume

Type or select values in entry fields.
Press Enter AFTER making all desired changes.

wait for this OK:

3: remove one copy from exited LV:

smit lvm --> logic volume -- > set Characteristic of a logical Volume -- > remove a copy from a logic volume

                               Remove Copies from a Logical Volume

when the copy accout updated to 1:

after ok:

step4:

let me check when the lv in two different disks case , check how to remove the stated lv:

smit lvm --> logical volume --> set Characteristic of a logical Volume -- > Add Copy to a logical Volume:

                                  Add Copies to a Logical Volume

Type or select values in entry fields.
Press Enter AFTER making all desired changes.

Command: OK stdout: no stderr: no

Before command completion, additional instructions may appear below.

You may see the different disks:

lslv">root@a05scpgapp01/>lslv -l tlv
tlv:/t

step5:

Now I want to remove the staled disk:

first should know which disk is the staled disk:

lspv">root@a05scpgapp01/>lspv hdisk0

ok, there is no staled partitions, let us check hdisk1:

lspv">root@a05scpgapp01/>lspv hdisk1

ok, let us remove the hdisk1:

after remove success, let us add copies in hdisk1,
and then do the syschronization:

                                  Add Copies to a Logical Volume

Type or select values in entry fields.
Press Enter AFTER making all desired changes.
