Replace storage subsystem

Jeongbae Min — Mon, 22 Mar 2004 16:42:56 GMT

Hello,

I want to replace current EMC 8430 Symm. to 1000 DMX. Cluster has one package and it has 97 PV in one PG. MAX PE per PV is 1078 and PE size is 4 M. I want to increase MAX PE per PV to 4000 while we are migration to new EMC DMX.

How can I proceed to migrate with new MAX PE?

Thanks in advance

Jeongbae

When you create the new VG or VGs on your new disk array, you just use the '-e' option to vgcreate (vgcreate -e 4000) when you create your VG's.

Err. Max PE per PV is fixed in stone at VG creation time. The only way to do it is to create a new VG like

vgcreate -e 4000 vg?? /dev/dsk/....

As such this cannot be done on-line...

Tim

Hello.

What is the MAX PE per PV and PE size for 11.00? We are planning on presenting large SAN LUN's (>300GB) to the o/s.

Thanks,

MAX PE per PV can be upto 65535 and PE size can be 256.

Therefore you can have 16,776 Gbytes of disk
