removing and reusing the disks in an FC60 array

[JOHN TURNER_2]

good afternoon

we have just run out of space on our testbed, we are using a FC60 diskarray, at present our luns consist of 2 disks using a 1:1 mirror. Is there an easy way to split the mirror, and have the luns as just 1 disk luns, and then re-use the other disks and create some new 1 disk luns

Hi John,

Issue a amcfg -D .

Then you will have to issue the following :

1. lvreduce -m1 lv_path
2. vgreduce gg_name pv_path
3. mv /etc/lvmtab /etc/lvmtab.backup
4. vgscan -v

Regards,
Simon

John,

easiest way is to use SAM as you do not want to remove completley.

commands are
amdsp -i to identify array
amdsp -a to display all data
amcfg to configue
man amcfg should help

Hi John ,

I believe this can not be done at OS level .
This split needs to be done on array. I dont have any idea fc60 will support single disk RAID 0 group . Please check for this.

It's been a while but if I recall correctly, the FC60 will not allow creation of LUNs without any redundancy (i.e RAID 0 or single disk).
