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.] Hello, Can IBM 3590 tape drive be online at the same time with both LPARs? If there is an LPAR that currently brought the *all drives* online, another LPAR will issue an IEE791I. IEE791I cuu VARY REJECTED - ASSIGNED TO ANOTHER SYSTEM I understand that both LPARs cannot use tape drives at the same time. I know there are products like CA-MIM to prevent this. Please do not consider separating the some drives and assigning it to both LPARs. Shared DASD can be online at the same time on both LPARs. Is it correct to recognize that the tape drives can also be online with both LPARs at the same time? If this is possible, could you please advise what settings are required? Current IOCP setting is bellow: CHPID PATH=(CSS(1),63),TYPE=FC,SHARED, X PARTITION=((CSS(1), X (PROD,TEST), X (=))), X PCHID=1EC CHPID PATH=(CSS(1),BA),TYPE=FC,SHARED, X PARTITION=((CSS(1), X (PROD,TEST), X (=))), X PCHID=2D0 E3590A10 CNTLUNIT CUNUMBR=3590,PATH=((CSS(1),63,BA)),CUADD=0, X UNIT=3590,UNITADD=((00,016)) EMIF0A10 IODEVICE CUNUMBR=3590,ADDRESS=(0A10,016),UNITADD=00, X UNIT=3590,STADET=Y Besy regards, Toyokazu Kobayashi ---------------------------------------------------------------------- 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.
