RE: Replacing a SCSI cable
by Link, Bill (OTS-EDH) 11 Oct '02

It's more or less "safe" if you are dealing with passive (differential) interfaces. If dealing with active (single-ended) interface I like to be sure that the device with the far end terminator is powered down. In any case, all the devices in the string have to be idle when you break the chain. SCSI controllers get most upset when they lose sight of their terminator while a bus transaction is taking place.

As long as there is no signal (ex- scanning SCSI card or Tape I/O) going down the SCSI line while the cables are being swapped I have never had a issue. It is nothing special about the Netapp. -----Original Message----- From: Mike Sphar [mailto:mike.sphar@Remedy.COM] Sent: Friday, October 11, 2002 10:44 AM To: toasters(a)mathworks.com Subject: RE: Replacing a SCSI cable Is that really safe?

RE: Replacing a SCSI cable
by Mike Sphar 11 Oct '02

Is that really safe? I was always taught never to connect or disconnect a SCSI cable on a powered-up system due to the possibility of damaging the SCSI controller, and I've actually seen that happen on a sparcstation once. Do the netapps and the tape drives have some additional technology that allows hot-swapping the scsi cable? -- Mike Sphar - Sr Systems Administrator - Remedy Corporation -----Original Message----- From: Mike Ball [mailto:MBall@datalink.com] Sent: Friday, October 11, … [View More]

Igor, You can hot swap the cable. I would sure no backup jobs are running on the Netapp and if you are using NDMP make sure you turn it off (ndmpd off) before swapping cables. It should work fine.

Two patches for netapp-top.pl
by Daniel Scheibli 10 Oct '02

10 Oct '02

Dear list, I have done two small patches for the netapp-top.pl script (http://now.netapp.com/NOW/download/tools/ntaptop/), which can be found at (http://www.edelbyte.org/html/s05c000m.htm in the patches section). The first one fixes an error when displaying hostsnames which can not be resolved, the other one limits the interval recalculation to more relevant cases. Hope you like it Daniel -- +++ GMX - Mail, Messaging & more http://www.gmx.net +++ NEU: Mit GMX ins Internet. Rund um … [View More]
