It may be that due to the dynamic nature of TDISK allocation, 240 contiguous cylinders are not available. Consider the following example based on a 100 cylinder TDISK area:
1) User A allocates 25 cylinders - 75 cylinders free (cyls 0-24 allocated, 25-99 free) 2) User B allocates 25 cylinders - 50 cylinders free (cyls 0-49 allocated, 50-99 free) 3) User C allocates 25 cylinders - 25 cylinders free (cyls 0-74 allocated, 75-99 free) 4) User B gives up his 25 cylinders - 50 cylinders free (cyls 0-24 and 50-74 allocated, 25-49 and 75-99 free) 5) User D attempts to allocate 50 cylinders and cannot, because 50 contiguous cylinders are not available. 6) User D allocates 25 cylinders, and gets it (cyls 0-74 allocated, 75-99 free) 7) User D allocates 25 cylinders, and gets it (cyls 0-99 allocated, 0 free) Regards, Bill Stephens Sr. Technology Analyst, High Availability SunGard Availability Services 10th floor 401 North Broad Street Philadelphia, PA 19108 Phone: (215) 351-1099 Fax: (215) 451-2045 [EMAIL PROTECTED] ___________________________________________ Keeping People and Information Connected (TM) http://www.availability.sungard.com Mary Zervos <[EMAIL PROTECTED] n.edu> To Sent by: VM/ESA [email protected] and z/VM cc Discussions <[EMAIL PROTECTED] Subject .UARK.EDU> Tdisk question 01/24/2006 09:17 AM Please respond to VM/ESA and z/VM Discussions <[EMAIL PROTECTED] .UARK.EDU> I have 500 cyl. of tdisk defined on one pack and 50 cyl. of tdisk defined on another. One user used the 50 cyl. on the second pack and about 24 users have used 215 cyl.(43%used) on the first pack. Why is it that I can only allocate a 130 cyl. maximum tdisk on the first pack but can then go ahead and allocate a 110 cyl. tdisk, instead of being able to allocate *one* 240 cyl. tdisk? Thanks for any help. Mary Zervos VM Systems Programmer Binghamton University [EMAIL PROTECTED]
