Unless you trust the sender, Don’t click links or open attachments as it may be a Phishing email, which can steal your Information and compromise your Computer.] I have observed the following problem: HMC is hanging up. I connect to HMC using web browser. So far so good. Then I click "logon", type user and password and... nothing happens. For hours. The same problem occurs when I try to logon using local console. The console is working, I can logon to SE directly, but not to the HMC. It is *not* single case, since three HMCs were affected. Two of them are ordered with z16 and reside inside CEC cabinet, the third is carried forward stand alone PC station (inherited from z15). The HMC version is 2.16.0. Note: for standalone HMC I simply removed PS cable and enforced PC reboot. It helped. I don't dare to repeat this brutal method for built in HMA/HMC. Note2: Both SE works like a charm. I can switch them, logon, etc. The second HMC inside the CEC box is also OK. Any clue? -- Radoslaw Skorupka Lodz, Poland ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ::DISCLAIMER:: ________________________________ The contents of this e-mail and any attachment(s) are confidential and intended for the named recipient(s) only.
