Dear Managers:
This is a question regarding adding a disk to an existing LSM
striped volume to an AlphaServer 8400. I'm new to LSM, I must
say.
Present configuration: 1 RZ28 (2.1 GB, system disk) and 7 RZ29
(4.3 GB, one of them enabled as swap, the rest form a striped
LSM volume on top of which there is an AdvFS domain enabled as
user space).
Disks to add: one RZ1C (4.3GB) and RZ1D (9.1GB). I've been
asked to increase swap space as well as user space.
I'd like to have a large LSM volume which contains all of the
user disks. I'm currently backing everything up and getting
ready for recreating the LSM volume, as I've been told it is
the only way of resizing an existing volume (if there is a non
destructive technique please let me know!)
I'd appreciate any advice on which choice is better (from a
performance point of view):
1) disable the existing swap, enable the 9.1 GB disk as swap,
and add the two 4.3 GB remaining disks to the LSM volume.
I would have eight disks in the same LSM volume, all of them
the same size.
2) add the 9.1 GB disk to the LSM volume and enable the 4.3
GB disk as swap. This way, my system would swap to two 4.3 GB
disks on different buses and the LSM volume would be formed by
six 4.3GB disks and one 9.1GB disk.
I've been reading the DU manuals but I'd be happy to get some
human advice... Thanks in advance.
Lucia.
