H135923 - INSUFFICIENT MEMORY ERROR WITH CHKDSK SYMPTOM: PC Servers with a disk partition of 17GB or larger may receive an insufficient memory error while running CHKDSK. -OR- CHKDSK may fail to complete (hang) when run on a large disk partition. The system may hang with only a partial error message displayed on the monitor. For example, the error message "HFS #####" may be displayed as "H" due to the hang. PROBLEM ISOLATION AIDS: - The system is a PC Server with an IBM RAID adapter. - The Operating System is OS/2 2.11, 2.11 SMP, 3.0, 4.0 or Warp Server. - CHKDSK is run on a disk partition of 17GB or larger. FIX: Do not replace any hardware; this is a software error. NOTE: CHKDSK runs for a long time on large partitions; it is NOT unusual for CHKDSK to run for 90 minutes or longer on a 17GB partition. CHKDSK may still be running even though it appears to be hung, so allow enough time for it to complete. Follow this procedure as a work-around: 1. Make a backup of the CONFIG.SYS file. 2. Edit the CONFIG.SYS file and remove the drive letter causing the error/hang from the AUTOCHECK parameter in the IFS (Install File System) statement. IFS=C: OS2 HPFS.IFS /CACHE:1024 /CRECL:64 /AUTOCHECK:CD <--drive letter 3. Restore data from a current backup. For additional information refer to OS/2 defect 155730 and/or APAR PJ18004.
