If you have any Os/2 based appliances, then you'd want to gracefully shut them down. Otherwise, they will run CHKDSK upon power up, and that takes forever. Examples of OS/2 based appliances include the older HMC's, 2074's, etc. Not sure if you can do that for the OS/2 based SE's, but, if you can, not a bad idea IMHO. (I believe the SE's and HMC are all Linux based on the z/9's. Linux recovery is fast enough to be left alone.)
There is a full power off function somewhere on the HMC or SE. I'd want to find and use that. You'd want to power off DS8100/Shark DASD units. Otherwise, these units will gracefully shut down using their internal batteries but will not come back on line until the batteries are completely recharged. That can take a very long time. Graceful shutdown and power off of other units (tape, VTS, etc) is likely a very good idea. Keep in mind that some units have 'secret' circuit breakers that trip upon full power loss. These 'secret' circuit breakers are supposed to be reset by the CE after power is restored and stable. Have your CE show you where these breakers are, or, better yet, have the CE on site for power up. HTH and good luck. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Matan Cohen Sent: Thursday, June 17, 2010 7:06 AM To: [email protected] Subject: taking down the machine - z9 series Hi, When the situation force you to taking down the machine (due to Electricity power cut) , after taking down the lpars. do you perform anything else beside deactivation of the CPC ? i met a diffrent opinion in this matter . -- best regards, matan cohen MF System Administrator. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html NOTICE: This electronic mail message and any files transmitted with it are intended exclusively for the individual or entity to which it is addressed.
