dasdh and dasdi are both swap, and they appear to be used as such: # swapon -s Filename Type Size Used Priority /dev/dasdh1 partition 10184 0 50 /dev/dasdi1 partition 102256 14968 100 -Channon -----Original Message----- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of Mark Post Sent: Sunday, October 14, 2007 6:23 PM To: [email protected] Subject: Re: Expanding SWAP space >>> On Sun, Oct 14, 2007 at 3:41 PM, in message <[EMAIL PROTECTED]>, "Quillen, Channon" <[EMAIL PROTECTED]> wrote: > SLES9 64-bit > > The existing swap disk (/dev/dasda1) wasn't large enough.

Anyone have notes on expanding the swap disk? In your case, you effectively added a brand new disk, so you have to follow the same steps you would normally. Those steps are exactly what you listing doing. The alternative would have been to use YaST to activate, format, partition, and then put a swap signature on the disk. > Also, I'm getting this error on another machine: > # fdasd -ask /dev/dasdh > /dev/dasdh is not an ECKD disk! This disk type is not supported! What does /proc/dasd/devices show? If it's not ECKD, fdasd won't touch it.
